This piece was rolled into a cone with the right edge lapped over the left edge and lying against the dotted line. In this position it was held by means of several brass fasteners of the kind shown in Fig. 56.
A mouthpiece was formed out of a block of wood in which a large hole had been drilled. The block was then cut away until the walls were quite thin. The hole was reamed out at the top, as shown in Fig. 57, and the outer surface was tapered so that the small end of the megaphone would fit snugly on it.
We planned to reach our camping grounds by way of the canal, and had provided for that purpose a large scow, which we expected to tow up to Lumberville and drag over to the river.
The Scow.
Our scow was made as follows: Two 3/4-inch pine boards, 12 inches wide and 12 feet long, were selected from Reddy’s
Fig. 58. Side pieces of the Scow. father’s lumber pile. These were used for the side pieces of the boat, and we tapered them off at the end to a width of 3-1/2 inches. This was done by making a straight cut from the end to a point three feet back along the edge of the board and then rounding off the edge with a draw-knife. When one board had been shaped, it was used as a pattern for the other, which was thus cut to exactly the same size. For the end pieces two strips, 4 inches wide and 2 feet 10-1/2 inches long, were sawed out of a 1-inch board. Then for the bottom we procured a number of 3/4-inch boards, 12 feet long and 8 inches wide, which we cut into 3-foot lengths. At Bill’s suggestion, before
