possilile. When rlecomiio.sition has reached the proper stage, add a quart of 

 sperm oil or any li(ini<l animal oil. Lard ma.v be used, but prairie-dog oil is 

 better. Then .-uld one oiinre of tineture of 8ilieriau nuisU. or Tonquin mnsk. 

 If this eannot lie prncnred. use in its place one ounce of dr.v. pulverised

After setting the traji. ajiply the .scent with a stick or straw or by pouring 

 from the bottle to the grass, weeds, or ground on the side of the trap opposite

The Bulletin also reconniiends the following method of poisoning wolves 

 and coyotes : — 



Xo poison has yet proved so effective as pure sulphate of strychnine. 

 provi<led the proper dose is used. Tlie most effective dose is 4 grains for 

 wolves and 2 grains for co.votes. The common o-grain gelatin capusules sold 

 b.v druggists will hold, if well filled, -t grains of str.vchiiine, and are better 

 than the larger capsules. TIii> regular 2-grain cnjisulrs should be used for 

 i-oyeti's. The capsules should be tilled, securely caiiped. and every trace of 

 the intensely bitter drug wii)ed from the outside. 



Each capsule should be inserted in a piece of beef .suet the size of a 

 walnut and the cavity securely chjsed to keep out the moisture. Lean meat 

 should not be used, as the juice soon dissolves the gelatin of the capsule. ThP 

 necessary number of poisoned baits may be prejiared and carried in a tin can 

 • >y iiail. They should never be handled exce[)t with gloved -laniis or forceps. 

 The baits ma.v be dropped from horseback along a scented drag line made b.v 

 dragging an old boue or piece of hide well saturated with the fetid scent, or 

 the.v may be placed around or partly under any carcass .m whiih the wolves or 

 coyotes are feeding or along trails which they arr in tlic b:ibit of following. 



Gelatin capsules quickl.v dissolve in the juices of the stomach. Strych- 

 nine taken on an empt.v stomach sometimes kills in a \rry few minutes, but 

 on a full stomach its action is much slower, and tlir aniuial may li;ive time to 

 travel a considerable distance.

Circular Xo. <;;_;, issued by the Lureaii of the Biological Survey, Washiu.g- 

 ton. I). ('., gives the results ubt.iincd during 1907, in the way of wolf destrue- 

 ticin. Tile methods of capturing wolves in cominciu tisc are three: — (1) 

 Ti-.-qiliiiig. (2) use of scents, and (3) poisoning. For traiijiiug. the best Xn. 4 

 double-spring trap should be used with a lie.Mvy stone as a drag. When 

 possible, the trap should be placed between two tufts of grass or weeds, so that 

 it can be reailil.v ai)proached from one side only. The traj), stone and chain 

 should be buried on a run-way. Scent is used to attract wolves to the vicinity 

 of the trap. Fetid bait is made by placing half a jicmnd of raw beef or 

 lenison in a wide-mouthed bottle and letting, it stand in a warm ]ilace for 

 from two to six weeks. When completel.y decomposed, add a iiuart of any 

 .■mimal oil, an ounce of inilverised asafetida and an ounce of Siberian or Tdii-
