forward motion a one-pound fragment of salmon is jammed 

 into an empty can, the can is carried on, and another 

 empty can follows it, into which another piece of fish is 

 thrust. This goes on without interruption, minute after 

 minute and hour after hour, so long as the supply of fish 

 holds out. 



The belt carrying the filled cans now throws them out 

 on a wide flat table surrounded by men, one of whom sets 

 them on end as he receives them from the machine. 

 Those that are completely full are whirled across the table 

 to a man who with a cloth wipes the grease or moisture 

 or salmon flesh from about the open end of the can, in 

 order that when the cover is soldered on, the solder may 

 take proper hold of the tin. Those not quite full are 

 thrown to another man, at whose right hand is a pile of 

 bits of salmon flesh. He fills the can and pushes it along 

 to the wiper. The latter, as soon as he has finished with 

 the can, slides it across to another who places a fragment 

 of tin on the contents in such a position that it will be 

 under the middle of the cover, which is now put on by 

 another man, standing near the end of the table. The filled 

 and covered cans are constantly gathered up and placed in 

 trays by two men, who carry them across a short passage 

 and set them down near a man who is attending to the 

 soldering machine. They are laid side by side on a belt 

 which runs down to a metal trough just as wide as a can 

 is high and deeper at one side than at the other, the lower 

 side being full of molten solder. The trough and solder 

 are kept hot by a blast beneath them. The cans are 

 moved forward by means of a heavy chain hanging over 

 them. The belt carries the cans down to this trough.

The edge of the cover where it meets the can rolls along 

 for ten or twelve feet through this molten solder, then the 

 can passes on to another belt, is tipped so that it stands on 

 its bottom and rides along on the belt to a point where
