More Binders,
in the form of a square, as A, B, C, D, in Fig. 88 are arranged. These form the support for the floor, and four more at the top of the corner or foundation poles will make a support for the roof. The rest of the work is simple; it is only necessary to lay a floor, put on a roof, and to board up the sides to have as snug a cabin as boys need want in summer-time. By using more piers you can make a foundation of any size.

When
The Bottom of the Pond
is hard sand, or stones, the basket-cribs may be built on shore in the same manner as described, but in this case it is neither necessary nor advisable to drive the stakes far into the earth. When finished the crib will hold together and may be removed from the land without dislocating the stakes, as the vines will hold them tightly in the structure.
Fig. 89.—Barrel Cribs.
You cannot possibly force your corner posts into the soil through hard sand or stones, and you must, therefore, be content to rest their lower ends upon the bottom, in which case make a stand for them by spiking two short boards, in the form of a cross, on the lower end of the posts, then slip your cribs over the posts (Fig. 89). While two boys hold the post and crib in place the others can fill the crib with cobble-stones, which will steady the post until it is made entirely secure by diagonal braces and the four binders, A, B, C, D. No matter how uneven the ends of the posts may be at first, the top of the binders, A, B, C, D, must be exactly level.
