 make a perfectly black line, even the thinnest. Higgins' "American Draw-

this. 



If not sufficiently skillful with the pen, make drawings with a hard 

 pencil on proper paper, showing all the lines you wish to appear and of 



the proper relative width.

Another "loco" plant. 



I have just had handed me by the editor of our Montana Stock Journal 

 a root with leaf buds on it, sent by a ranchman from Augusta, Montana, 

 with the declaration that it is called " loco " weed, also " rattle weed, 

 and that it is " killing horses." 



The root and plant sent me is undoubtedly Oxytropis lagopus Nutt., 

 and lam astounded to hear of its ill-repute at Augusta. I am so much 

 astounded that I think a mistake must have been made by the ranch- 

 men of Augusta in identifying the plant that does the mischief. Have 

 your readers any knowledge of this matter? F. D. Kelsey.
