Carbon bi-sulphide is both inflammable and explosive and is to be 

 handled with extreme care. It is best used in wet weather. The gas 

 that proceeds from it tends to descend. Some users place the liquid in

 simple method of determining whether any burrowing animal is occupy-

 removed.

 pensive in construction, which is shown in Figures 10 and 10- A is used for 

 vermin generally by both Mr. Wallace Evans and Mr. Harry T. Rogers. 

 It can be made at home, the dimensions being, width, 16 inches, length,

 trap known. The floor is of solid wood and a frame constructed of 1 x 2

 9 inches from the rear, its ends passing through holes bored in angle irons 

 screwed to the floor, which permit the rod to revolve. Attached to the
