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 ivareliousemen. — Any individual, firm, corporation, or 

 association engaged in the business of maintaining and operating cold-storage 

 w:;reliouses in which food products are stored for hire or compensation, shall be 

 called a public cold-storage warehouseman. 



3. Private cold-storage icarehousemen. — 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 ptiblic 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 probaljly 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 

 tHj^ 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
