BUIXETIN OF THE UNITED STATES FISH COMMISSION. 469 



arc liozeii. In 18S0 Mr. D. W. Davis obtained a patent (22G390) for 

 packini^- fish and finely-crushed ice in a barrel and freezing the same 

 solid, the fish being so stowed as not to come in contact with one 

 another. 



In Bostorn, Kew York, and other cities entire buildings of three to 

 five stories or floors are now made into fish-freezers and cold storage 

 for fish. The most common method of producing the cold air req- 

 uisite for freezing is by the use of ice and salt in metallic chambers 

 or large tubes, which pass perpendicularly through the freezing-room. 

 The freezing-room is provided with double walls interlined with some 

 non-conductor. The fish are either hung on hooks or spread on shelves 

 until frozen, when they are removed to the cold storage-rooms and kept 

 for months, if need be, before marketing.
