The case is made exactly in the same manner as the former one, and has the same dimensions, but has no horizontal partition, only a cross-piece in the front, half an inch square.
The inside of the back you must paint to represent a cliff and sky, or you can paste a coloured picture of the same on it.
The yacht is to be 5 in. long, and is to be set in a sea of silk, which will be described [further on]. If you prefer it, a full-rigged ship can be substituted for the yacht. For the machinery you will require, as before, an eight-day clock movement, some brass wire, and three or four pulley-wheels. [Fig. 5] shows the front view of the mechanism when complete, and [Fig. 6] the end view of the same.

As was the case in preparing the works for the windmill, you will require to make some alteration in the wheels, but in this case, as the hour and minute movement will be required for the starting gear, the minute spindle only is to be soldered to the central spindle, and the small flat wheel retained in its place. The escapement wheel must also be retained. B ([Fig. 5]) is one of the wooden pulleys, 1 in. in diameter, fixed to the minute-hand spindle, and is in connection with another pulley-wheel of the same size (B), turning on a screw fixed in a block of wood fastened to the floor-board in such a position that the centres of the two pulleys are the same height from the floor and 41⁄2 in. apart. O is a lever of wire about 7 in. long, working on a pivot passing through it about 21⁄2 in. from the end C. This end is connected with the keel of the boat, and the other end is weighted, to balance the boat.
