U. S. Department of Agriculture,

Sir: I have the honor to transmit herewith a manuscript entitled 
"The Cold Curing of American Cheese," by C. F. Doane, expert in 
charge of cheese investigations of the Dairy Division of this Bureau. 
This paper, which is one in a series on Investigations in the Manufac- 
ture and Curing of Cheese, contains a report of recent experiments by 
the Dairy Division, prefaced b}^ a review of previous work in cold 
curing. In view of the undoubted value of this information for the 
cheese industry of the country I recommend its publication as a bul- 
letin of this Bureau. 
Respectfully, 
A. D. Melvin, 
Chief of Bureau. 
Hon. James Wilson, 
Secretary of Agriculture.
