INJURIOUS MULLIPEDES. 121 



REMEDIES. 



No remedies other than hand picking have been tried in the 

 houses at Orono. It has been found that the milHpedes work 

 at night mostly, and early in the morning are found near 

 the surface of the ground. During the day, they burrow and are 

 more difficult to find. The morning, therefore, is the best time 

 to hunt for them. They do more injury in sub-watered than in 

 surface watered beds. We would suggest putting slices of pota- 

 toes poisoned with strychnine in the beds. Of course, if this or 

 any other poison is used, the radishes should be carefully washed 

 before marketing. Chips, of wood scattered in the beds afford 

 hiding places and these could be examined in the morning for 

 specimens. A more troublesome way is to heat the dirt used in 

 the beds. This could be done by connecting a heating box con- 

 taining a coil of perforated pipes with the engine, or by forcing 

 steam into the dirt in the beds by means of a hose and nozzle.
