FISHERIES OF THE UNITED STATES. 37 



A. J. CHASE, Boston, Massachusetts : 



Chase's Cold Blast Refrigerator. (33.) 



" This scientific system of refrigerating with ice, or ice and salt, or other 

 freezing mixture, is the invention of Andrew J. Chase, of Boston, 

 Massachusetts. It has heen in use now five years. The strong points 

 of this system are claimed to lie in the fact that it is adapted to 

 all purposes, as it gives any temperature from 24° helow freezing 

 to 42° above zero. The iuternal circulation of the air is very brisk 

 and dry, a necessary condition for preserving perishable goods. 

 Thus far this refrigerator has been used principally for heavy work, 

 or upon a large scale. At this time there are about 2,000 cold-blast 

 cars in use, transporting dressed beef from the West to all the prin- 

 cipal cities and towns from Maine to New Orleans and Florida. 

 Thirty-two large English steamships have been fitted for transport- 

 ing fresh meats to Europe. These have a capacity ranging from 800 

 to 1,800 quarters of beef each. The leading hotels and markets of 

 the States are also fitted with these important structures. Cold- 

 blast preserving houses are getting very popular in all parts of the 

 country. Boston has the largest one in the world, just finished. 

 Fish dealers are beginning to see that the old slop and slime method 

 of packing in ice must very soon give place to the dry handling. Mr. 

 Chase makes contracts for putting up buildings with all the improved 

 appliances, guaranteeing any temperature desired. He also makes 

 a specialty of cooling and ventilating buildings or passenger cars." — 

 (From letter of A. J. Chase.) 



Chase's Monitor Display Eefrigerator. (33.) 



"This refrigerator is used by those who wish to display small goods, 

 such as print butter, chops, steaks, and fish. It is very economical 

 in the use of ice, costing but a few cents to run it during the day. It 

 is made in three sizes at present prices, $15, $20, and $25. Those 

 may be used with ice and ice water, or with salt and ice, according 

 to the temperature required." — (From letter of A. J. Chase.) 



OREN M. CHASE, Detroit, Michigan : 



*A glass hatching jar, provided with a glass tube, by means of which
