Mr. EDWIN ALLEN, of New Brunswick, N. J., writes : 



" Have had my sixteen cows on your grating many months, and find it only neces- 

 sary to clean gutter once a month. It is a splendid arrangement to save all the 

 manure, which I cart directly to the field before the valuable salts are washed out 

 by rains. The cows do not object to standing or lying on it. They stand and get 

 up much easier from this floor being level, instead of slanting as in the old way. 

 I use plaster, and sweepings from a button factory, as an absorbent and deodorizer 

 for manure. Shall order grating for another row of cows next season." [He has 

 just ordered for sixteen more cows.]
