Not alone with the gladiolus but with other 

 bulbs it seemed that the animals took special de- 

 light in attacking the choicest plants. And the 

 question of their destruction became finally a 

 very urgent one. 



Numerous methods of combating the pests 

 were tested. A double box trap set in gopher 

 holes was cumbersome and not very effective. 

 An awkward iron trap was supposed to catch the 

 gopher when he poked his nose against the trig- 

 ger, but missed fire or failed to score a hit of tener

 was tried and given up. Attempts to smoke out 

 the animals proved ineffective, as the gopher in-

Bisulphid of carbon, which gives off a poison-

 poison, commonly called strychnin, placed on a 

 piece of apple, potato, or carrot, combined with

 failed the other might prove effective. But in 

 spite of all these methods the gophers multiplied,

 A few years ago, however, a gopher gun was
