INCUBATION. 



DR. WIGHT S APPARATUS. 



This plan for watering fowls originated, as I understand, with 

 Dr. Eben Wight. I received a brief description of it from Dr. 

 W., which has been mislaid, but the plan shows for itself what 

 it is, and how constructed. It appears that a keg is suspended, 

 as shown in the cut, with an opening at the top to receive the 

 water, large enough to receive the water direct from the pail, 

 and which may be closed by a door hung on hinges.. A tube 

 of some kind, either lead or wood, connects the keg with 

 the trough below, and the water at the lower end of this 

 tube is made to run out very slowly, so a-s not to exhaust 

 the supply above short of twenty-four hours, when a new sup- 

 ply is furnished. By this means, the water is always pure in 

 the trough. 



A cheap conductor of the water from the keg to the trough, 

 may be made of -wood, square, with a small channel in the 

 centre. A common water pail may be made to perform the 

 office of this apparatus, by inserting a faucet in the side, near 

 the bottom ; then place it on a stool, with a bowl below to 

 receive the water. The pail should be placed in the shade in 

 warm weather, andcovered. 



INCUBATION. 



Instead of going into an analysis of all the causes that 

 produce a desire in hens to incubate, or sit, I shall simply
