TOOLS OF THE CRAFT. 



The implements in use in the troughs are few and 

 simple. Wisp-brooms to clean troughs and trays from 

 ilime. Strong feathers in wooden handles to move 

 eggs that may be washed in heaps — the wing feathers of 

 geese are best, because the quills are stififer. Nippers 

 for removing dead eggs or other substances are best 

 made of red cedar; a piece 7 inches long by i^ inches 

 wide and ^ inch thick will do. Bore a |-inch hole an 

 inch and a half from one end and rip from the other end 

 into the hole with a saw and then trim down until you 

 have a pair of nippers that are springy and will open 

 themselves. Either flatten and hollow the ends to hold 

 an tgg, or better still, whip on loops of fine brass wire. 

 Then make square frames of heavier brass wire and put 

 in a wooden handle, the frames being 3 inches square. 

 Cover them with "millinet," such as milliners use, sew 

 it on perfectly fiat and it is handy for picking up lots of 

 eggs that have got ofif the trays or for other purposes. 

 Strong glass tubes, about three-quarters of an inch 

 outside diameter, and ten inches long, are very handy 

 for picking up eggs or embryos for examination. Stop 

 one end with the finger and put the other end near the 

 object to be lifted. Remove the finger quickly and let 

 the water rush in with the eggs, dirt or whatever you 

 may wish. Close the top again and also the bottom 

 and then you can examine the object at leisure. 



These things, with a microscope and thermometer, 

 are all that 1 need to hatch several millions of trout. Go
