"Oh, it's a long story too long to tell. Thurl was at the bottom of those accidents. He knew as well as I did that the mine was rich better than I did, for that matter, for we discovered before we ran him out of Alaska that he had made secret borings on the property. But what I did not know until a few hours ago was that he had actually uncovered what we uncovered only yesterday the mother lode.
It is only known by borings, and some of it may be of the same age as Number 3; but I believe it to be for the most part of more modern origin, consisting of the wreck of all the older gravel, including Number 3, and formed during the last hollowing out and deepening of the valley immediately before the commencement of the growth of peat.
Before commencing the excavation for the foundations of a dam, it is most essential that the character of the soil or rock should be examined carefully, by sinking a succession of small shafts, not mere borings, along the site, so that the depth to which the trench will have to be carried, and the amount of ground water likely to be encountered, can be reliably ascertained, as this portion of the work cannot be otherwise estimated, and as it may bear a very large proportion of the total expense of construction, and in certain cases may demonstrate that the site is altogether unsuitable for the proposed purpose.
They dig, by preference, against the base of the cover; here they make several borings, without any reason, so far as I can see, the bed of soil being everywhere equally assailable away from the brick; the first point sounded is abandoned for a second, which is rejected in its turn. A third and a fourth are tried; then another and yet another. At the sixth point the selection is made.
Each of them had "the reverse side cut perfectly flat, and with the borings to attach them to some other object." They were "in a veritable funereal armoury." At the same time, according to Reichel and Mr. How are we to understand this poet? He is such an erudite archaeologist that, in the seventh century, he knows and carefully describes a helmet of the Mycenaean prime.
We must ascertain in a direct fashion whether the cell into which the auger has been driven several times over actually contains several occupants in addition to the larva of the Mason-bee. When the Leucopses had finished their borings, I waited a few days longer so as to give the young grubs time to develop a little, which would make my examination easier.
In their report to the Secretary of War, under date of May 2, 1907, they said: "We found that all of the locks, of the dimensions now proposed, will rest upon rock of such character that it will furnish a safe and stable foundation." Subsequent new borings, conducted by the present Commission, have fully confirmed this verdict. They show that the locks will rest on rock for their entire length.
The two railroad lines coming from 32d Street in Manhattan, and curving to the left at Second Avenue, are about 34 ft. apart between centers at First Avenue, and it was convenient to make the shaft large enough to cover both lines. Borings had shown that the excavation for the tunnels would break out of the rock about 200 ft. east of First Avenue.
It includes two hundred and fifty feet of solid salt, in several distinct beds, each sealed within the shales of the series. Would you expect to find ancient beds of rock salt inclosed in beds of pervious sandstone? The salt beds of the Salina are of great value. They are reached by well borings, and their brines are evaporated by solar heat and by boiling.
When required for use, take 1 part of the mixture, and 20 parts of clean borings, mix thoroughly, and add a sufficient quantity of water. A little grindstone added improves the cement. This is the conversion of the surface of wrought iron into steel, for the purpose of adapting it to receive a polish, or to bear friction, &c.
