appear to escape tick infestation while young, and when they subsequently become 

 infested with large numbers of ticks they succumb to the virulent form of the disease. 

 The only treatment from which the author obtained any favorable results consisted 

 in administering 1 lb. of Epsom salts and hypodermic doses of 30 grains of quinine 

 every 3 hours. Brief notes are given on the occurrence of blackleg, anthrax, glanders, 

 and tuberculosis in the 8tate. 



List of plants of known or suspected poisonous properties which occur 

 within the State, E. V. Wilcox [Montana Sta. Bid. 22, pp. 51-53). — A list is given 

 of 14 species of plants which are known to the writer as being poisonous, or which 

 have been suspected by stock growers as being injurious to stock. Of the species 

 mentioned the purple and tall larkspurs, aconite, lupine, death camass, nightshade, 

 and water hemlock are known to have caused the death of a number of animals, and 

 loco w^eeds are suspected as being injurious. The author investigated a number of 

 cases of poison reputed to be due to certain plants, but upon investigation found that 

 the evidence was either of a very unsubstantial nature, or the suspected plant was in 

 no way connected with the death of the animals. 



Lupines as plants poisonous to stock, E. V. Wilcox [Montana. Sta. Bui. 22, 

 pp. 37-45). — Brief notes are given on a numljer of cases of poisoning from lupine 

 which were observed in Montana. In 1 case 100 out of 200 bucks fed upon lupine 

 hay died witliin a few hours after feeding. In another case a considerable loss of 

 sheep was suffered from allowing them to eat ripe lupine upon the range. After 

 autumn snowstorms in 1898 the loss of sheep from eating lupine upon the range in 

 Montana amounted to 2,000, 1,150 of which were from 1 band. A few cases of lupine 

 poisoning in horses are also recorded. The most severe losses from lupine poisoning 

 have been due to eating these plants in the form of hay, a large quantity of which is 

 annually cut in the State. The poisoning in all cases seemed to be due to eating the 

 ripe or nearly ripe seed, which would appear to contain the poisonous principles in 

 greater a])un(lance than other parts of the plant. A brief bibliography is also given. 



Cattle poisoning by the tall larkspur, E.V.Wilcox [Montana Sta. Bui. 22, 

 pp. 45-47). — Notes are given on the appearance and distribution of Delphinium r/Iau- 

 cum in Montana. An outbreak of cattle poisoning which occurred in the Gallatin 

 Basin, and which resulted in the death of 40 cattle, was investigated. It was found 

 that the poisoning was due to the species of larkspur just mentioned, and that this 

 plant had been apparently eaten in unusual quantities, on account of the fact that 

 other green forage was covered by a recent fall of snow. 



Poisoning of stock by the water hemlock, E. V. Wilcox [Montana Sta. Bui. 

 22, p. 4S). — Brief notes on cases of poisoning from this plant in man, sheep, and cat- 

 tle. In cattle the symptoms were severe \i2i\n, accompanied by cerebral excitement 

 and spasms. In 1 case the animal died within 15 minutes after the appearance of the 

 first symptoms. 



The poisoning of cattle by smutty oat hay, E. V. Wilcox [Montana Sta. Bui. 

 22, i>. 51). — During the winter of 1898 a dairyman lost 12 cows in feeding smutty oat 

 hay. The oats had become so badly smutted that they were cut for hay rather than 

 grain. Out of 30 cows which received 1 feed of the smutty oat hay 12 died within 18 

 h(jurs after feeding, with symptoms of gastric disturbances and cerebral excitement. 



Ergotism in horses, E. Y. Wilcox [Montana Sta. Bui. 22, pp. 49,50). — Ergot is 

 reported as very abundant on a considerable variety of native grasses in the State. 

 A number of cases of poisoning observed in horses are believed to be forms of ergot- 

 ism. The symptoms were a gradual paralysis beginning with the muscles of the 

 throat; horses were soon unable to swallow, and later became unable to stand, and 

 died of general paralysis. Death occurred in the majority of cases within from 6 to 

 12 hours. In 2 cases recovery took place after the administration of strychnin 

 hypodermically and whisky by the mouth
