Hampstead town was formed as a result of 1739 decision fixing boundary line between the New Hampshire and Massachusetts.

Although such methods may be tolerated when the maximum unit-loading is not great (as for a breakwater or a wharf), it is seldom that a satisfactory foundation can be thus obtained for heavy bridge piers and similar structures. A caisson is literally a box; and an Open caisson is virtually a huge box which is built on shore and launched in very much the same way as a vessel, and which is sunk on the site of the proposed pier. (See Fig. 61.) The box is made somewhat larger than the proposed pier, which is started on the bottom of the box. The sinking of the box is usually accomplished by the building of the pier inside of the box, the weight of the pier lowering it until it reaches the bed prepared for it on the subsoil. The preparation of this bed involves the same difficulties and the same objections as those already referred to in the adoption of concrete cribs. The bottom of the box is essentially a large platforms made of heavy concrete piles and planking. The sides of the caissons have sometimes been made so that they are merely tied to the bottom by means of numerous tie- rods extending from the top down to the extended platforms at the bottom, where they are hooked into large iron rings. When the pier is complete above the water line so that the caisson is no longer needed, the tie-rods may be loosened by unscrewing nuts at the top. The rods may then be unhooked, and nearly all the timber in the sides of the caisson will be loosened and may be recovered. Very strict requirements of the superstructure would demand, so that the superstructure may have its intended alignment, even though the pier is six inches or even a foot out of its intended position. A pneumatic caisson is essentially a large inverted box on which a pier is built, and inside of which work may be done because the water is forced out of the box by compressed air. If an inverted tumbler is forced down into a bowl of water, the large air space within the tumbler gives some idea of the possibilities of working within the caisson. If the tumbler is forced to the bottom of the bowl, the possibilities of working on a river bottom are somewhat exemplified. It is, of course, necessary to have a means of communication between this working chamber and the surface; and it is likewise necessary to have an air-lock through which workmen (and perhaps materials) may pass. The process of sinking resembles in many points that described in the previous section. The caisson is built on shore, is launched, and is towed to its position. Sometimes, for the sake of economy (provided timber is cheap), that portion of the pier from the top of the working chamber to within a few feet below the low-water line, may be built as a timber crib and filled with loose stone or gravel merely to weight it down. This method is usually cheaper than concrete cutting; and the timber, being always under water, is durable. As in the previous section, the caisson sinks as the material is removed from the base, the 'sinking being assisted by the additional weight on the top. The only essential difference between, the two processes consists in the method of removing the material from under the caisson. The greatest depth to which such a caisson has ever been sunk is about 110 feet below the water line. This depth was reached in sinking one of the piers for the St. Louis Bridge. At such depths the air pressure per square inch is about 48 pounds, which is between three and four times the normal atmospheric pressure. Elaborate precautions are necessary to prevent leakage of air at such a pressure. Only men with strong constitutions and in perfect health can work in such an air pressure, and even then four hours work per day in two shifts of two hours each is considered a good day's work at these depths.
