in sandy, porous soils, and if these be too dry at the time of 

 treatment the insects within range are not long enough exposed 

 to the vapour to be killed. 



In using bisulphide of carbon as a remedy against wirevvorms 

 the following points should be noted : — 



(1) The soil must not be too wet or too dry at the time of 

 use, and after applying it there should be no cultural operations 

 for a week at the very least, longer would be better. (2) The 

 treatment should be in time, i.e., whenever the plants are known 

 to be attacked, not when they are dying off. ( 3) Make a hole 

 (with a stick), beginning 3 or 4 in. from the plant, and passing 

 down in an oblique direction till a point is reached rather below 

 the root. (4) Pour in a teaspoonful of bisulphide of carbon for 

 each plant treated and quickly stamp the soil in over the hole 

 and press down. (5) The material must not touch the roots: 

 the liquid will harm the plant but the vapour is harmless. 



The plants treated will be quite free from any poisonous pro- 

 perties and thoroughly wholesome. If the pest be taken in 

 time one injection should be enough. 



The Board will be glad to receive particulars of any experi- 

 ments in the use of this material. The following are the points 

 which should be noted : — (a) The date and mode of treatment, 

 the date when seed was sown, when damage was first noted, and 

 the age of the plants at the time ; (b) General result of the 

 experiment with a comparison between treated and untreated 

 area. The dates and other particulars should be written down 

 at the time and not given from memory. 



An experiment carefully performed on these lines would be 

 of value.

conclusions arrived at in this Journal for March last (p. 733), 



which were practically identical with those of the Industrial
