of Fowler's solution, while cattle may be given hypodermic injections 

 of strychnin. These doses should be continued for at least a month. 

 Care should be taken in the use of strychnin, as locoed animals are 

 very sensitive to its use. It is better that doses for cattle should 

 not exceed three-twentieths or four-twentieths of a grain. Never, in 

 the case of a large animal, should more than one-half grain be given. 



In the case of locoed sheep upon the range, if the number is small, 

 it is not profitable to spend any time or trouble with them. It is 

 better to slaughter them immediately, as a locoed sheep will teach 

 others the same habit. If, however, a number of locoed sheep can 

 be separated and, like the cattle, be turned into an alfalfa field, 

 most of them are likely to recover. Sheep may be helped by doses 

 of one- twentieth grain of strychnin, but ordinarily, on account of the 

 small value of individual animals, it is not profitable to spend the 

 time which is necessary to insure their recovery. 



In handling animals in a loco country it should be remembered 

 that all domestic animals are more or less imitative, and loco eaters 

 are likely to teach others to do the same thing. Therefore, so far 

 as possible, all animals that have acquired the habit of loco eating 

 should be separated from the others. 



LARKSPURS. 



A great many species of larkspurs grow in the western stock 

 ranges, and they are widely distributed throughout the mountain 

 regions which are used for pasturage. These plants when in blos- 

 som are very easily recognized by the peculiar form of the flower. 

 Before blossoming there are a few plants with which they may be 

 confused by a person who is not versed in botany, but it is not 

 particularly difficult for the ordinary observer, after a little experi- 

 ence, to recognize larkspurs in all stages of growth. While there is 

 a large number of species, all may be grouped under the two general 

 heads of tall larkspurs and low larkspurs. 



TALL LARKSPURS. 



The tall larkspurs in their maturity reacn a height of 4, or even 

 6 and 8 feet. They are perennials and grow in great abundance 

 in the high mountain regions, ordinarily preferring damp and shel- 

 tered places, such as are found in mountain valleys and under trees. 

 Under some circumstances, however, they may grow in considerable 

 abundance in the open. All the tall larkspurs agree in the form of 

 the leaf, which is well illustrated in Plates VII and VIII. The 

 flowers, with the spur from which the plant gets its name, are very 

 characteristic in their form and in most species vary in their colore 

 through various shades of violet, blue, and purple. Before the 

 plants are mature the leaves may be confused with those of the
