"But sometimes there will be hardly a drop of water in the spring, and then there is trouble. Everybody is sorry then, for we have to haul water from the creek in barrels, and it isn't as good to drink as the spring water."

"Is that the only queer thing?" asked Daddy Bunker.

"No. The most remarkable thing about it," went on Uncle Fred, "is that every time the spring goes dry some of my cattle are taken away. I suppose you could call it stolen, though I don't like to think that any of my neighbors would steal. I used to think the cattle wandered away, but since none of them wander back again I feel pretty sure they must be taken on purpose."

"And every time the spring dries up the cattle are taken?" asked Mrs.

Bunker, while the six little Bunkers listened eagerly to Uncle Fred's story.

"Almost every time. I don't know what causes it."

"Maybe the cows drink up all the water," said Russ.

"No, cattle don't come near the spring," said Mr. Bell. "They are on the far end of the ranch. It is a puzzle to me; about as much of a puzzle as the ghost must have been at Great Hedge, before you found out about it."

"So you came East to consult some engineers about the spring," remarked Daddy Bunker. "Do you think they can help you?"

"Well, you know there are engineers who make a study of all kinds of water; of springs, lakes, rivers, and so on," explained Uncle Fred.

"They are water-engineers just as others are steam or electrical engineers. I thought I'd ask them the reasons for springs going dry.

Some of them may know something about the water in Montana, and they can tell me if there are underground rivers or lakes that might do something to my spring.

"Anyhow I had some other business in New York, so while I was attending to that, and coming on here to get you folks, I thought I'd see the engineers."

"And have you seen any yet?" asked his sister.

"Not yet. I'm going to in a day or so. But I stopped at a store and ordered----"

Before Uncle Fred could say what it was he had ordered the doorbell rang again. This time it could not be Daddy Bunker coming in, as he was already at home.

Norah, who went to open the door, could be heard speaking to some one.

"Oh, and it's a message you have for Mr. Bell, is it?" she said. "Well, come in and don't be standin' there in the wet rain."

"A message for me!" exclaimed Uncle Fred. "I hope it isn't any bad news from my ranch--about more cattle being taken."

CHAPTER V

PACKING UP

"Somebody for you, Mr. Bell," announced Norah, as she opened wider the door of the sitting room where the six little Bunkers, Uncle Fred and the others were gathered. "It's a boy, and he has a package."

"Then it can't be a telegram containing bad news," said Uncle Fred.

"They don't come in packages, unless there's a lot of 'em, and I hardly would get that many. I'll see what it is."

The boy was not a telegraph messenger after all, but a special delivery lad from the post-office, and the package he had for Uncle Fred was a book.

"Oh, it's a book I sent for to New York," said the ranchman after he had given the boy ten cents, and had opened the package.

"It's a book that tells about springs, and the rocks underneath the earth where the water comes from. I thought I'd read about springs so I'd learn something about the queer one on my ranch," Uncle Fred said to Daddy Bunker. "I heard about this book, sent to New York for it, and asked them to send it to me here by special delivery. Now I can read what I want to know about water."

"Will you read us a story out of the book?" asked Margy. "I like stories."

"I don't believe there are any stories in this book," said Uncle Fred with a laugh.

"Could you tell us one?" asked Mun Bun.

"About cowboys!" exclaimed Russ.

"And Indians!" added Laddie.

"Well, I guess I could think of a story, if I tried real hard," answered Uncle Fred, laughing.

The six little Bunkers gathered about his chair, and, laying aside the book that the special delivery messenger had brought, the ranchman told the children some wonderful stories.

He told them how, once, his cattle all ran away in a mad rush called a "stampede," and how he and his cowboys had to ride after them on ponies, firing their big revolvers, to turn the steers back from a deep gully.

"And did you stop 'em?" asked Russ, his eyes wide open in wonder and excitement.

"Oh, yes. But it was hard work," answered his uncle.

Then Mr. Bell told about a big prairie fire. On the flat, level fields, where he pastured his cattle, grew long gra.s.s. When this gets dry it burns very easily, and, once started, it is hard to stop.

"And how did you stop it?" asked Rose, when her uncle had told about the blazing miles of gra.s.s.

"We got a lot of men and horses and plows," he answered, "and plowed a wide strip of land in front of the fire. When the flames got to the bare ground there was nothing for them to burn, and the wind was not strong enough to carry them over to where there was more gra.s.s. So we saved our ranch houses."

"Do you live in a house on your ranch?" asked Laddie.

"Why, of course we do!" laughed Uncle Fred. "What did you think we lived in?"

"Tents, like the Indians."

"Oh, no, we have houses. But they aren't as nice as yours here in Pineville," said the ranchman. "I have a house to myself where I live with Captain Roy, and there is another house where the cowboys live.

Then there is still another house where they eat their meals. This has a lot of big windows in it that can be opened wide on a hot day."

"Who is Captain Roy?" asked Russ. "Is he an old soldier, like Jerry Simms?"

"Yes, Captain Robert Roy used to be in the United States army," answered Uncle Fred. "He is retired now, and he helps me at the ranch. He is a partner of mine, and he looks after things while I am away. You six little Bunkers will like him, for he loves children."

"I wish we could hurry up and get out there!" sighed Russ.

"Well, I think the best place for my little chickens to hurry to is--_bed_!" laughed Mother Bunker. "Go to bed now, and morning will soon come, so we can talk about going to Uncle Fred's."

The children did not want to go to bed, but they always minded their mother, unless they forgot and did something she had told them not to.

But this time there was no chance to forget.
