move forward, and their spoons descend the pond ; and as the 

 eccentric moves forward the back- weights jerk the spoons Tip the 

 ponds, scattering the meat very evenly and at regular intervals. 

 The amount of motion is regulated by the position of the rod, or, 

 in other words, by the amount of slack between the handle of the 

 spoon and the end of the rod. Thus each of the four 20-feets can 

 be fed at a different rate with any alteration of the number of turns 

 of the shaft. If it is wished to increase or decrease the power, it 

 is easily done by altering the depth of the immersed portion of the 

 water-wheel. For this purpose grooves are cut in the sides of 

 the trough behind the wheel, and boards are slipped in to deepen 

 the water, which can thus be dammed back on the floats of the 

 wheel to any desired depth. I should have mentioned that the 

 wheel is undershot. The advantages of this invention are great.
