 there were 53,203 carcasses and 717,749 packages, the weight being 

 231,144,938 pounds. These figures show an increase in the exports of 

 beef and mutton, but a falling off in pork, the total difference being 

 (in round numbers) 26,000,000 pounds less than in 1900 — the gain of 

 15,000,000 in beef being offset by a loss of 40,000,000 in pork. In 1900 

 there was an increase over 1899 of 77,000,000 pounds in beef, and a 

 decrease of 6,000,000 pounds in pork.

MICROSCOPIC INSPECTION OF PORK. 



The number of carcasses of pork examined was 733,196, classified 

 as follows: Class A (free of all appearance of trichinae), 715,529, or 

 97.59 per cent; Class B (containing trichina-like bodies or disinte- 

 grating trichintB), 8,668, or 1.18 per cent; Class C (containing living 

 trichinae), 8,999, or 1.23 per cent. There is little change in tlie per- 

 centages; Class A slightly increased, with a corresponding diminution 

 in Class C. 



Thei-e were 9,001 trichinous carcasses disposed of during the year; 

 the weight of these was 2,003,858 pounds. Over half of this quantity 

 was made into cooked meat; the remainder was tanked. 



The decrease in the exports of microscopically examined pork con- 

 tinued, so that the quantitj' inspected for export amounted to less 

 than two-thirds of that of the year before. The number of certificates 

 issued was 6,188; the number of packages was 127,017, with a weight 

 of 35,942,404 pounds. For comparison the quantities inspected for
