238 THE AMERICAN MONTHLY [Au 



Vexatious and burdensome restrictions have constantly to 

 be met, but the trade has continued to grow notwithstand- 

 ing - . During-the fiscal year 1892 there were 38, 152,874 pounds 

 inspected for export, 22,025,698 pounds going to countries 

 requiring inspection and 16,127,176 to countries not requir- 

 ing it, while in 1899 the total shipment was 108,928,195, of 

 which 108,858,149 went countries requiring inspection and 

 70,046 to countries not requiring it. 



The regulations for this work provide that a microscopic 

 examination be made of all hog products which are for ex- 

 port to countries requiring such examination. The follow- 

 ing from the regulations shows the method of operation: 



When the slaughtered hog is passed into the cooling room 

 of said establishment, the inspector in charge, or his as- 

 sistants, will take from each carcass three samples of mus- 

 cle — one from the "pillar of the diaphragm," one from the 

 psoas muscle, and the other from the inner aspect of the 

 shoulder, and also from the base of the tongue when that 

 organ is retained for exportation ; and said samples will be 

 placed in small tin boxes, and a numbered tag will be placed 

 upon the carcass from which said samples have been taken, 

 and a duplicate of said tag will be placed in the box with 

 said samples. The small boxes will be placed in a large tin 

 box provided with a lock. The boxes containing the sam- 

 ples from the hogs in the cooling room so tagged will be 

 taken to the microscopist for such establishment, who shall 

 thereupon cause a microscopic examination of the contents 

 of each box containing samples to be made, and shall fur- 

 nish a written report to the inspector, giving the result of 

 said microscopic examination, together with the numbers 

 of all carcasses affected with trichinae. The samplesof pork 

 microscopically examined shall be classified as follows : 



Class A. — Samples in which there are no signs of tri- 

 chinae, living or dead, calcified cysts, or other bodies or 

 substances having any resemblance to trichinae or trichinae 

 cysts. 



Class B. — Samples in which they are disintegrated tri- 

 chinae cysts, calcified trichinae cysts or bodies having any 

 resemblance thereto.
