10 BULLETIN" TO, U. S. DEPARTMENT OF AGRICULTURE. 
COLD-STORAGE DEFINITIONS. 
For the purpose of licensing and regulating cold-storage plants the 
following definitions were promulgated by the President. They are 
used by the Food Administration and by the Department of Agri- 
culture : 
1. Cold-storage warehouse. — A cold-storage warehouse shall mean any place 
artificially or mechanically cooled to or below a temperature of 45 degrees above 
zero Fahrenheit in which food products are placed and held for thirty days 
or more. 
2. Public cold-storage 'warehousemen. — Any individual, firm, corporation, or 
association engaged in the business of maintaining and operating cold-storage 
warehouses in which food products are stored for hire or compensation, shall be 
called a public cold-storage warehouseman. 
3. Private cold-storage warehousemen. — Any individual, firm, corporation, 
or association that maintains and operates as any adjunct to their business, 
cold-storage warehouses for the storage of food products exclusively owned or 
dealt in by them, shall be called a private cold-storage warehouseman. 
4. Combined public and private cold-storage warehousemen. — Any individual, 
firm, corporation, or association which combines a public cold-storage ware- 
house business with a storage of commodities which directly or indirectly it 
owns, deals in, or otherwise has an interest in shall be called a combined public 
and private cold-storage warehouseman. 
COMPILING THE REPORTS. 
In addition to showing the actual quantities of the different com- 
modities as reported from the warehouses, certain comparisons are 
made with the reports of other months, in order to show the relative 
amount in storage compared with previous dates and the relative 
increase or decrease in holdings during the month. In preparing 
the first reports showing the cold-storage holdings of apples for the 
season 1914—15, the comparison was made with the holdings of the 
season 1912-13, as it was believed that the holdings of that season 
were more nearly normal than those of the season 1913-11. Except 
for the first season, the holdings of the current year were compared 
with the holdings on the same date of the previous year. For the 
first season only, the total holdings of the United States were used in 
the comparison ; but at the beginning of the season of 1915-16, the re- 
ports showed the holdings in each State. Later in that season it was 
decided to adopt a more convenient and probably more valuable 
grouping, and the reports are now issued showing the holdings of 
sections. The sectional grouping as finally adopted is shown in the 
accompanying map (fig. 3). 
Besides comparing the reports of the current month with those of 
the same month in the preceding year, a comparison is made between 
the holdings of the current month and the holdings on December 1. 
This is to show the percentage of the amount stored for the season
