As the Screamer rounded to and made fast in the eddy, the Ledge gang were engaged in using the system of derricks, which since the final anchoring had never needed an hour's additional work. They were moving back from the landing-wharf the big cut stones required to lay the first course of masonry, the work to begin as soon as the controversy over the proper level of the concrete was settled.

With the making fast of the Screamer to the floating buoys in the eddy, the life-boat from the Ledge pulled alongside, and landed Sanford, Carleton, Captain Joe, Caleb, and the skipper,-Lonny Bowles carrying the transit and rod as carefully as if they had been two long icicles. When the party reached the Ledge the concrete was found to be awash with three feet of water; nothing of the ma.s.s itself could be seen by the naked eye. It was therefore apparent that if the dispute was to be settled it could be done only by a series of exact measurements. Carleton showed every evidence of satisfaction. He had begun to suspect he might be wrong, but his obstinacy sustained him.

Now that the disk was covered with water there was still reason for dispute.

Caleb squeezed himself into his diving-dress, and began operations, Captain Joe fastening the water-tight cuffs over his wrists, leaving his hands free. The diver then picked up the rod with its adjustable target and plunged across the shallow basin, the water coming up to his hips. Sanford meanwhile arranged the tripod on the platform, leveled his instrument, directing Caleb where to hold the rod, and began his survey. Captain Joe stood one side recording his findings with a big blue lead pencil on a short strip of plank.

The first entries showed that the two segments of the circle-the opposite segments, southeast and northwest-varied barely three tenths of an inch in height. This, of course, was immaterial over so large a surface. The result proved conclusively that Carleton's claim that one section of the concrete was six inches too low was absurd.

"I'm afraid I shall have to decide against you this time, Mr.

Carleton," said Sanford pleasantly. "Run your eye through this transit; you can see yourself what it shows."

"Right or wrong," broke out Carleton, now thoroughly angry, both over his defeat and at the half-concealed, jeering remarks of the men, "it's got to go up six inches, or not a cut stone will be laid. That's what I'm here for, and what I say _goes_."

"But please take the transit and see for yourself, Mr. Carleton,"

urged Sanford.

"I don't know nothin' about _your_ transit, nor who fixed it to suit you," snarled Carleton.

Sanford bit his lip, and made no answer. There were more important things to be done in the building of a light than the resenting of such insults or quarreling with a superintendent. The skipper, however, to whom the superintendent was a first experience, and who took his answer as in some way a reflection on his own veracity, walked quickly toward him with his fist tightly clinched. His big frame towered over Carleton's.

"Thank you, Captain Brandt," said Sanford, noticing the skipper's expression and intent. "But Mr. Carleton isn't in earnest. _His_ transit is not here, and we cannot tell who fixed that."

The men laughed, and the skipper stopped and stood aside, awaiting any further developments that might require his aid.

"In view of these measurements," asked Sanford, as he held before Carleton's eyes the piece of plank bearing Captain Joe's record, "do you still order the six inches of concrete put in?"

"Certainly I do," said Carleton. His ugly temper was gradually being hidden under an air of authority. Sanford's tact had regained him a debating position.

"And you take the responsibility of the change?"

"I do," replied Carleton in a bl.u.s.tering voice.

"Then please put that order in writing," said Sanford quietly, "and I will see it done as soon as the tide lowers."

Carleton's manner changed; he saw the pit that lay before him. If he were wrong, the written order would fix his responsibility; without that telltale record he could deny afterward having given the order, if good policy so demanded.

"Well, that ain't necessary; you go ahead," said Carleton, with less vehemence.

"I think it is, Mr. Carleton. You ask me to alter a bench-mark level which I know to be right, and which every man about us knows to be right. You refuse a written certificate if I do not carry out your orders, and yet you expect me to commit this engineering crime because of your personal opinion,-an opinion which you now refuse to back up by your signature."

"I ain't given you a single written order this season: why should I now?" in an evasive tone.

"Because up to this time you have asked for nothing unreasonable. Then you refuse?"

"I do, and I'm not to be bulldozed, neither."

"Caleb," said Sanford, with the air of a man who had made up his mind, raising his voice to the diver, still standing in the water, "put that rod on the edge of the iron band."

Caleb felt around under the water with his foot, found the band, and placed on it the end of the rod. Sanford carefully adjusted the instrument.

"What does it measure?"

"Thirteen feet six inches, sir!" shouted Caleb.

"Lonny Bowles," continued Sanford, "take three or four of the men and go along the breakwater and see if Caleb is right."

The men scrambled over the rocks, Lonny plunging into the water beside Caleb, so as to get closer to the rod.

"Thirteen feet six inches!" came back the voices of Lonny and the others, speaking successively.

"Now, Captain Joe, look through this eyepiece and see if you find the red quartered target in the centre of the spider-web lines. You, too, skipper."

The men put their eyes to the gla.s.s, each announcing that he saw the red of the disk.

"Now, Caleb, make your way across to the northwest derrick, and hold the rod on the band there."

The old diver waded across the concrete, and held the rod and target over his head. The men followed him around the breakwater,-all except Bowles, who, being as wet as he could be, plunged in waist-deep.

Sanford turned the transit without disturbing the tripod, and adjusted it until the lens covered the target.

"Raise it a little, Caleb!" shouted Sanford,-"so! What is she now?"

"Thirteen feet six inches and-a-half!"

"Right! How is it, men?"

"Thirteen six and a half!" came back the replies, after each man had a.s.sured himself.

"Now bring me a clean, dry plank, Captain Joe," said Sanford. "That's too small," as the captain held out the short piece containing the record. Clean planks were scarce on the cement-stained work; dry ones were never found.

Everybody went in search of a suitable plank. Carleton looked on at this pantomime with a curl on his lips, and now and then a little shiver of uncertain fear creeping over him. Sanford's quiet, determined manner puzzled him.

"What's all this circus about?" he broke out impatiently.

"One minute, Mr. Carleton. I want to make a record which will be big enough for the men to sign; one that won't get astray, lost, or stolen."

"What's the matter with this?" asked Captain Joe, opening the wooden door of the new part of the shanty. "Ye can't lose this 'less ye take away the house."

"That's the very thing!" exclaimed Sanford. "Swing her wide open, Captain Joe. Please give me that big blue pencil."

When the door flew back it was as white and clean as a freshly scrubbed pine table.

Sanford wrote as follows:-

_August 29_, Shark Ledge Light.

We, the undersigned, certify that the concrete disk is perfectly level except opposite the northwest derrick, where it is three tenths of an inch too high. We further certify that Superintendent Carleton orders the concrete raised six inches on the southeast segment, and refuses to permit any cut stone to be set until this is done.
