NEW TYPE OF JARS FOR HATCHING. 
BY W. E. MEEHAN. 
Some superintendents of hatcheries in Pennsylvania were not 
pertectly satisfied with the type of jars used for hatching and 
asked me to try to design something more satisfactory. 
I designed a jar which is now in use in some of our batteries, 
and I believe is in use in one other state and is giving entire 
satisfaction. ‘There is no patent on the device. There is no con- 
traction at the top, the lip is much larger than in the other jars 
and wider, and the stem is done away with and a simple plate 
of glass set on the bottom. ‘The bottom is round and formed 
hke the bottom at the McDonald. This jar will hold as many 
eggs as the Chase or Downing jar, and more than the McDonald, 
and can be set up close to the battery. The jar not needing as 
large a lip as is necessary on some jars, because of the body being 
perfectly straight, allows the jar to set close to the trough; the 
amount of water required is not so great as is necessary in cer- 
tain types of jars. A small amount of water will keep the eggs 
moving very nicely. We have been using it in our hatcheries 
with very great success and the men believe it to be better than 
some of the types that we have been using heretofore. One other 
state also has been using it with marked success. 
Mr. Clark: What is the difference between that and other 
jars; I cannot see it. 
Mr. Meehan: The Downing improved comes in this way: 
The MeDonald jar is shaped something like this: 
which makes it difficult to clean, and so with the Chase jar.
