engages the trillis lantern pinion at E, and thereby drives the other wheel X, and thus, by the engagement of the teeth into the trillis Y, makes the stone rotate. The rest is easily seen from the figure. With this mill, one only needs to take care that one strikes the correct proportion of the wheels, namely: if the large wheel S rotates once, the wheel X should have completed its rotation two or three times, and thus the millstone may complete its movement, fast or slow, in the opposite proportion, as may be necessary.

The XXI. Figure.

A Horse Mill.

This is, like the previous one, a mill which can be driven by a horse. This happens through the large horizontal wheel B, which is toothed on the top and on the face, and thereby engages in the sticks at A and C; thus, through this, the wheel D, which then further grips the trillis E, rotating, also makes the stone F run. In this mill, the division of the wheels in good proportion to one another, as noted in the previous one, must not be overlooked. At H and I, it can be seen how one should raise and lower the current mill and adjust the millstone with it.

The XXII. Figure.

A Horse Mill.

The current mill, which again can be easily driven by a horse G or other animal, also has a horizontal, upward-toothed wheel A, which engages in the horizontal trillis B, and thus causes the rotation of the wheel C. This wheel then further drives the upright trillis D, and finally makes the millstone F run. At E, one can easily arrange the stick for the bolting of the flour, and just as

has been shown above for the hand mills.

The XXIII. Figure.

A Horse Mill.

Here is depicted a type of horse mill which, through the fall of water (where one has the opportunity for it), comes to the aid of the horse and can drive the mill all the more easily. This happens when the horse is harnessed to the arm of the axle tree A, and thus leads the same around with it. Through the large trillis B, in whose sticks the large toothed wheel C, together with its axle tree K, rotates, it lifts the water upwards through the square paddles which go into the box G, and makes it flow out again through the fall D. Which outflow then further leads the paddles E and, together with them, the shaft F, along with the millstone I, around.

Note: This mill can be set up in two ways: namely, where one has running water and a strong fall for it, or where one has standing water, a strong spring, or a deep well whose water is brought up to a height and made to fall again through D onto the paddle wheel E.

The XXIV. Figure.

A Weight Mill.

This is a type of mill which is pulled by large weights where there is a lack of water. The large weight A is hung onto the double pulleys B. Through the double pulleys B, as well as through the other simple ones C, D, and E, a fairly strong rope must be pulled through and firmly attached to the cylinder or the axle tree F. On the axle tree F, a spur wheel is further arranged, which engages with its cogs into the trillis G,
