"Sorry," I said, "we don't take ladies. At least, not to the Late Mesozoic."

This wasn't strictly true, but I felt we were running enough risks, going after a little-known fauna, without dragging in people's domestic entanglements. Nothing against s.e.x, you understand. Marvelous inst.i.tution and all that, but not where it interferes with my living.

"Oh, nonsense!" said James. "If she wants to go, she'll go. She skis and flies my airplane, so why shouldn't she-"

"Against the firm's policy," I said.

"She can keep out of the way when we run up against the dangerous ones," he said.

"No, sorry."

"d.a.m.n it!" said he, getting red. "After all, I'm paying you a goodly sum, and I'm ent.i.tled to take whoever I please."

"You can't hire me to do anything against my best judgment," I said. "If that's how you feel, get another guide."

"All right, I will," he said. "And I'll tell all my friends you're a G.o.d-d.a.m.ned-" Well, he said a lot of things I won't repeat, until I told him to get out of the office or I'd throw him out.

I was sitting in the office and thinking sadly of all that lovely money James would have paid me if I hadn't been so stiff-necked, when in came my other lamb, one August Holtzinger. This was a little slim pale chap with gla.s.ses, polite and formal: Holtzinger sat on the edge of his chair and said: "Uh-Mr. Rivers, I don't want you to think I'm here under false pretenses. I'm really not much of an outdoorsman, and I'll probably be scared to death when I see a real dinosaur. But I'm determined to hang a dinosaur head over my fireplace or die in the attempt."

"Most of us are frightened at first," I soothed him, "though it doesn't do to show it." And little by little I got the story out of him.

While James had always been wallowing in the stuff, Holtzinger was a local product who'd only lately come into the real thing. He'd had a little business here in St. Louis and just about made ends meet when an uncle cashed in his chips somewhere and left little Augie the pile.

Now Holtzinger had acquired a fiancee and was building a big house. When it was finished, they'd be married and move into it. And one furnishing he demanded was a ceratopsian head over the fireplace. Those are the ones with the big horned heads with a parrot-beak and a frill over the neck, you know. You have to think twice about collecting them, because if you put a seven-foot Triceratops head into a small living room, there's apt to be no room left for anything else.

We were talking about this when in came a girl: a small girl in her twenties, quite ordinary looking, and crying.

"Augie!" she cried. "You can't! You mustn't! You'll be killed!" She grabbed him round the knees and said to me: "Mr. Rivers, you mustn't take him! He's all I've got! He'll never stand the hardships!"

"My dear young lady," I said, "I should hate to cause you distress, but it's up to Mr. Holtzinger to decide whether he wishes to retain my services."

"It's no use, Claire," said Holtzinger. "I'm going, though I'll probably hate every minute of it."

"What's that, old boy?" I said. "If you hate it, why go? Did you lose a bet, or something?"

"No," said Holtzinger. "It's this way. Uh-I'm a completely undistinguished kind of guy. I'm not brilliant or big or strong or handsome. I'm just an ordinary Midwestern small businessman. You never even notice me at Rotary luncheons, I fit in so perfectly.

"But that doesn't say I'm satisfied. I've always hankered to go to far places and do big things. I'd like to be a glamorous, adventurous sort of guy. Like you, Mr. Rivers."

"Oh, come," I said. "Professional hunting may seem glamorous to you, but to me it's just a living."

He shook his head. "Nope. You know what I mean. Well, now I've got this legacy, I could settle down to play bridge and golf the rest of my life, and try to act like I wasn't bored. But I'm determined to do something with some color in it, once at least. Since there's no more real big-game hunting in the present, I'm gonna shoot a dinosaur and hang his head over my mantel if it's the last thing I do. I'll never be happy otherwise."

Well, Holtzinger and his girl argued, but he wouldn't give in. She made me swear to take the best care of her Augie and departed, sniffling.

When Holtzinger had left, who should come in but my vile-tempered friend Courtney James? He apologized for insulting me, though you could hardly say he groveled.

"I don't really have a bad temper," he said, "except when people won't cooperate with me. Then I sometimes get mad. But so long as they're cooperative I'm not hard to get along with."

I knew that by "cooperate" he meant to do whatever Courtney James wanted, but I didn't press the point. "How about Miss Bartram?" I asked.

"We had a row," he said. "I'm through with women. So, if there's no hard feelings, let's go on from where we left off."

"Very well," I said, business being business.

The Raja and I decided to make it a joint safari to eighty-five million years ago: the Early Upper Cretaceous, or the Middle Cretaceous as some American geologists call it. It's about the best period for dinosaur in Missouri. You'll find some individual species a little larger in the Late Upper Cretaceous, but the period we were going to gives a wider variety.

Now, as to our equipment: The Raja and I each had a Continental .6oo, like the one I showed you, and a few smaller guns. At this time we hadn't worked up much capital and had no spare .6oos to rent.

August Holtzinger said he would rent a gun, as he expected this to be his only safari, and there's no point in spending over a thousand dollars for a gun you'll shoot only a few times. But, since we had no spare .6oos, his choice lay between buying one of those and renting one of our smaller pieces.

We drove into the country and set up a target to let him try the .6oo. Holtzinger heaved up the gun and let fly. He missed completely, and the kick knocked him flat on his back.

He got up, looking paler than ever, and handed me back the gun, saying: "Uh-I think I'd better try something smaller."

When his shoulder stopped hurting, I tried him out on the smaller rifles. He took a fancy to my Winchester 70, chambered for the ~ magnum cartridge. This is an excellent all-round gun-perfect for the big cats and bears, but a little light for elephant and definitely light for dinosaur. I should never have given in, but I was in a hurry, and it might have taken months to have a new .6oo made to order for him. James already had a gun, a Holland & Holland .5oo double express, which is almost in a cla.s.s with the .6oo.

Both sahibs had done a bit of shooting, so I didn't worry about their accuracy. Shooting dinosaur is not a matter of extreme accuracy, but of sound judgment and smooth coordination so you shan't catch twigs in the mechanism of your gun, or fall into holes, or climb a small tree that the dinosaur can pluck you out of, or blow your guide's head off.

People used to hunting mammals sometimes try to shoot a dinosaur in the brain. That's the silliest thing you can do, because dinosaur haven't got any. To be exact, they have a little lump of tissue the size of a tennis ball on the front end of their spines, and how are you going to hit that when it's imbedded in a six-foot skull?

The only safe rule with dinosaur is: always try for a heart shot. They have big hearts, over a hundred pounds in the largest species, and a couple of .6oo slugs through the heart will slow them up, at least. The problem is to get the slugs through that mountain of meat around it.

Well, we appeared at Prochaska's laboratory one rainy morning: James and Holtzinger, the Raja and I, our herder Beauregard Black, three helpers, a cook, and twelve jacks.

The transition chamber is a little cubbyhole the size of a small lift. My routine is for the men with the guns to go first in case a hungry theropod is standing near the machine when it arrives. So the two sahibs, the Raja, and I crowded into the chamber with our guns and packs. The operator squeezed in after us, closed the door, and fiddled with his dials. He set the thing for April twenty-fourth, eighty-five million B.C., and pressed the red b.u.t.ton. The lights went out, leaving the chamber lit by a little battery-operated lamp. James and Holtzinger looked pretty green, but that may have been the lighting. The Raja and I had been through all this before, so the vibration and vertigo didn't bother us.

The little spinning black hands of the dials slowed down and stopped. The operator looked at his ground-level gauge and turned the handwheel that raised the chamber so it shouldn't materialize underground. Then he pressed another b.u.t.ton, and the door slid open.

No matter how often I do it, I get a frightful thrill out of stepping into a bygone era. The operator had raised the chamber a foot above ground level, so I jumped down, my gun ready. The others came after.

"Right-ho," I said to the chamber wallah, and he closed the door. The chamber disappeared, and we looked around. There weren't any dinosaur in sight, nothing but lizards.

In this period, the chamber materializes on top of a rocky rise, from which you can see in all directions as far as the haze will let you. To the west, you see the arm of the Kansas Sea that reaches across Missouri and the big swamp around the bayhead where the sauropods live.

To the north is a low range that the Raja named the Janpur Hills, after the Indian kingdom his forebears once ruled. To the east, the land slopes up to a plateau, good for ceratopsians, while to the south is flat country with more sauropod swamps and lots of ornithopod: duckbill and iguanodont.

The finest thing about the Cretaceous is the climate: balmy like the South Sea Islands, but not so muggy as most Jura.s.sic climates. It was spring, with dwarf magnolias in bloom all over.

A thing about this landscape is that it combines a fairly high rainfall with an open type of vegetation cover. That is, the gra.s.ses hadn't yet evolved to the point of forming solid carpets over all the open ground. So the ground is thick with laurel, sa.s.safras, and other shrubs, with bare earth between. There are big thickets of palmettos and ferns. The trees round the hill are mostly cycads, standing singly and in copses. You'd call 'em palms. Down towards the Kansas Sea are more cycads and willows, while the uplands are covered with screw pine and ginkgoes.

Now, I'm no b.l.o.o.d.y poet-the Raja writes the stuff, not me-but I can appreciate a beautiful scene. One of the helpers had come through the machine with two of the jacks and was pegging them out, and I was looking through the haze and sniffing the air, when a gun went off behind me-bang! bang!

I whirled round, and there was Courtney James with his .5oo, and an omithomime legging it for cover fifty yards away. The ornithomimes are medium-sized running dinosaurs, slender things with long necks and legs, like a cross between a lizard and an ostrich. This kind is about seven feet tall and weighs as much as a man. The beggar had wandered out of the nearest copse, and James gave him both barrels. Missed.

I was upset, as trigger-happy sahibs are as much a menace to their party as theropods. I yelled: "d.a.m.n it, you idiot! I thought you weren't to shoot without a word from me?"

"And who the h.e.l.l are you to tell me when I'll shoot my own gun?" he said.

We had a rare old row until Holtzinger and the Raja got us calmed down. I explained: "Look here, Mr. James, I've got reasons. If you shoot off all your ammunition before the trip's over, your gun won't be available in a pinch, as it's the only one of its caliber. If you empty both barrels at an unimportant target, what would happen if a big theropod charged before you could reload? Finally, it's not sporting to shoot everything in sight, just to hear the gun go off. Do you understand?"

"Yeah, I guess so," he said.

The rest of the party came through the machine, and we pitched our camp a safe distance from the materializing place. Our first task was to get fresh meat. For a twenty-one-day safari like this, we calculate our food requirements closely, so we can make out on tinned stuff and concentrates if we must, but we count on killing at least one piece of meat. When that's butchered, we go off on a short tour, stopping at four or five camping places to hunt and arriving back at base a few days before the chamber is due to appear.

Holtzinger, as I said, wanted a ceratopsian head, any kind. James insisted on just one head: a tyrannosaur. Then everybody'd think he'd shot the most dangerous game of all time.

Fact is, the tyrannosaur's overrated. He's more a carrion eater than an active predator, though he'll snap you up if he gets the chance. He's less dangerous than some of the other theropods-the flesh eaters, you know-such as the smaller Gorgosaurus from the period we were in. But everybody's read about the tyrant lizard, and he does have the biggest head of the theropods.

The one in our period isn't the rex, which is later and a bit bigger and more specialized. It's the trionyches, with the forelimbs not quite so reduced, though they're still too small for anything but picking the brute's teeth after a meal.

When camp was pitched, we still had the afternoon. So the Raja and I took our sahibs on their first hunt. We had a map of the local terrain from previous trips.

The Raja and I have worked out a system for dinosaur hunting. We split into two groups of two men each and walk parallel from twenty to forty yards apart. Each group has a sahib in front and a guide following, telling him where to go. We tell the sahibs we put them in front so they shall have the first shot. Well, that's true, but another reason is they're always tripping and falling with their guns c.o.c.ked, and if the guide were in front he'd get shot.

The reason for two groups is that if a dinosaur starts for one, the other gets a good heart shot from the side.

As we walked, there was the usual rustle of lizards scuttling out of the way: little fellows, quick as a flash and colored like all the jewels in Tiffany's, and big gray ones that hiss at you as they plod off. There were tortoises and a few little snakes. Birds with beaks full of teeth flapped off squawking. And always there was that marvelous mild Cretaceous air. Makes a chap want to take his clothes off and dance with vine leaves in his hair, if you know what I mean.

Our sahibs soon found that Mesozoic country is cut up into millions of nullahs-gullies, you'd say. Walking is one long scramble, up and down, up and down.

We'd been scrambling for an hour, and the sahibs were soaked with sweat and had their tongues hanging out, when the Raja whistled. He'd spotted a group of bonehead feeding on cycad shoots.

These are the troodonts, small omithopods about the size of men with a bulge on top of their heads that makes them look almost intelligent. Means nothing, because the bulge is solid bone. The males b.u.t.t each other with these heads in fighting over the females.

These chaps would drop down on all fours, munch up a shoot, then stand up and look around. They're warier than most dinosaur, because they're the favorite food of the big theropods.

People sometimes a.s.sume that because dinosaur are so stupid, their senses must be dim, too. But it's not so. Some, like the sauropods, are pretty dim-sensed, but most have good smell and eyesight and fair hearing. Their weakness is that having no minds, they have no memories. Hence, out of sight, out of mind. When a big theropod comes slavering after you, your best defense is to hide in a nullah or behind a bush, and if he can neither see you nor smell you he'll just wander off.

We skulked up behind a patch of palmetto downwind from the bonehead. I whispered to James: "You've had a shot already today. Hold your fire until Holtzinger shoots, and then shoot only if he misses or if the beast is getting away wounded."

"Uh-huh," said James.

We separated, he with the Raja and Holtzinger with me. This got to be our regular arrangement. James and I got on each other's nerves, but the Raja's a friendly, sentimental sort of bloke n.o.body can help liking.

We crawled round the palmetto patch on opposite sides, and Holtzinger got up to shoot. You daren't shoot a heavy-caliber rifle p.r.o.ne. There's not enough give, and the kick can break your shoulder.

Holtzinger sighted round the last few fronds of palmetto. I saw his barrel wobbling and waving. Then he lowered his gun and tucked it under his arm to wipe his gla.s.ses.

Off went James's gun, both barrels again.

The biggest bonehead went down, rolling and thrashing. The others ran away on their hindlegs in great leaps, their heads jerking and their tails sticking up behind.

"Put your gun on safety," I said to Holtzinger, who'd started forward. By the time we got to the bonehead, James was standing over it, breaking open his gun and blowing out the barrels. He looked as smug as if he'd come into another million and was asking the Raja to take his picture with his foot on the game.

I said: "I thought you were to give Holtzinger the first shot?"

"h.e.l.l, I waited," he said, "and he took so long I thought he must have gotten buck fever. If we stood around long enough, they'd see us or smell us."

There was something in what he said, but his way of saying it put my monkey up. I said: "If that sort of thing happens once more, we'll leave you in camp the next time we go out."

"Now, gentlemen," said the Raja. "After all, Reggie, these aren't experienced hunters."

"What now?" said Holtzinger. "Haul him back ourselves or send out the men?"

"We'll sling him under the pole," I said. "He weighs under two hundred."

The pole was a telescoping aluminium carrying pole I had in my pack, with padded yokes on the ends. I brought it because, in such eras, you can't count on finding saplings strong enough for proper poles on the spot.

The Raja and I cleaned our bonehead to lighten him and tied him to the pole. The flies began to light on the offal by thousands. Scienlists say they're not true flies in the modern sense, but they look and act like flies. There's one huge four-winged carrion fly that flies with a distinctive deep thrumming note.

The rest of the afternoon we sweated under that pole, taking turn about. The lizards scuttled out of the way, and the flies buzzed round the carca.s.s.

We got to camp just before sunset, feeling as if we could eat the whole bonehead at one meal. The boys had the camp running smoothly, so we sat down for our tot of whiskey, feeling like lords of creation, while the cook broiled bonehead steaks.

Holtzinger said: "Uh-if I kill a ceratopsian, how do we get his head back?"

I explained: "If the ground permits, we lash it to the patent aluminium roller frame and sled it in."

"How much does a head like that weigh?" he asked.

"Depends on the age and the species," I told him. "The biggest weigh over a ton, but most run between five hundred and a thousand pounds."

"And all the ground's rough like it was today?"

"Most of it," I said. "You see, it's the combination of the open vegetation cover and the moderately high rainfall. Erosion is frightfully rapid."

"And who hauls the head on its little sled?"

"Everybody with a hand," I said. "A big head would need every ounce of muscle in this party. On such a job there's no place for side."

"Oh," said Holtzinger. I could see he was wondering whether a ceratopsian head would be worth the effort.

The next couple of days we trekked round the neighborhood. Nothing worth shooting; only a herd of ornithomimes, which went bounding off like a lot of ballet dancers. Otherwise there were only the usual lizards and pterosaurs and birds and insects. There's a big lace-winged fly that bites dinosaurs, so, as you can imagine, its beak makes nothing of a human skin. One made Holtzinger leap and dance like a Red Indian when it bit him through his shirt. James joshed him about it, saying: "What's all the fuss over one little bug?"

The second night, during the Raja's watch, James gave a yell that brought us all out of our tents with rifles. All that had happened was that a dinosaur tick had crawled in with him and started drilling under his armpit. Since it's as big as your thumb even when it hasn't fed, he was understandably startled. Luckily he got it before it had taken its pint of blood. He'd pulled Holtzinger's leg pretty hard about the fly bite, so now Holtzinger repeated the words: "What's all the fuss over one little bug, buddy?"

James squashed the tick underfoot with a grunt, not much liking to be hoist by his own what-d'you-call-it.

We packed up and started on our circuit. We meant to take the sahibs first to the sauropod swamp, more to see the wildlife than to collect anything.

From where the transition chamber materializes, the sauropod swamp looks like a couple of hours' walk, but it's really an all-day scramble. The first part is easy, as it's downhill and the brush isn't heavy. Then, as you get near the swamp, the cycads and willows grow so thickly that you have to worm your way among them.

I led the party to a sandy ridge on the border of the swamp, as it was pretty bare of vegetation and afforded a fine view. When we got to the ridge, the sun was about to go down. A couple of crocs slipped off into the water. The sahibs were so tired that they flopped down in the sand as if dead.
