or lowered, also revolved in the arc of a quarter circle. To this 

 can is attached a supply pipe to conduct kerosene oil from the 

 can to a perforated burner suspended over the water. This con- 

 ductor has a globe valve in it to regulate the supply of oil. The 

 conductor is :^-inch gaspipe al)OUt 12 inches long. The burner 

 is ^-inch gaspipe 6 inches long, with cap at the end. The perfor- 

 ations in the burner are i -32-inch in diameter, antl should not 

 exceed 20 in number. The burner is made of larger pipe than 

 the conductor to it, as a convenience in winding asbestos wick- 

 ing, which is loosely wound upon it and fastened with fine wire. 

 Cotton batting or bagging can be used for this purpose, but is 

 not as good. The burner when wound with asbestos resembles 

 in shape a bobbin of cotton. A shade is necessary to protect the 

 fishermen from the heat and glare of the light, and for conven- 

 ience should be detachable. Galvanized sheet-iron is good for 

 this purpose. For night fishing the light is suspended over the 

 bow of the boat, the standard being screwed into a cast-iron foot, 

 which latter is attached to the boat by means of a lag screw. 

 The same method of fishing is employed whether by day or 

 night, the jack-light being the only additional feature at night. 

 The gill-net is then thrown around the spawning bed, the fishing 

 boat is run inside, and a man with a dip-net stands in the bow 

 ready to dip the fish. He directs the guidance of the boat, which 

 is propelled by one oarsman. The fish are easily seen on their 

 beds in from one to five feet of water, and remain undisturbed 

 until the dip-net approaches them. If they lie facing the net, 

 they can be usually picked up. Sometimes a pair can be taken 

 together. When several are on the same bed, those that are 

 frightened away invariably start directly for deep water. In their 

 sudden plunge they run against the gill-net, are caught by their 

 jaws, and in their struggles wind up in the net. The cork floats 

 of the net are painted white to facilitate seeing them at this stage, 

 and the fish thus caught is easily taken by holding the dip-net 

 under it and then shaking out the gill-net. The sport is exciting, 

 and fishermen forget the time of night, even if the thermometer 

 registers far below freezing point. This method of fishing 

 with dip-nets was first employed in taking the lake trout 

 (s. namaycush), and has been in vogue in New Hampshire for 

 several years, the use of the gill-net not being required. It re- 

 quired much urging and practical illustration before the sj^yawn- 

 takers would believe that brook trout could be dipped up in the 

 same manner. As fast as dipped up, the fish are put into tanks 

 of water and kept in the boat until forty or fifty trout are cap-
