floors ; and the lower floor being about 6 feet below the level of 
the ground, built in with heavy walls and thoroughly under- 
drained, gives a low even temperature all the year round. The 
floor is covered with stone flagging nicely laid in cement, so as 
to make a perfectly tight bottom where no accumulation of water 
or filth can find an entrance. It may be observed here that all 
condensing factories should have basements similarly constructed, 
since, by securing a low and uniform temperature, the milk can 
be kept in better order, and a better product can be secured. 
The main building is 40 X 68 feet, three stories ; with wings.
