Up to the present it docs not appear to have been generally tried in tlie West Indies. It is used in Grenada as a means of freeing nutmegs from weevils, and in Trinidad against ants and for pests of grain, seed, etc.; but as an insecti- cide it is by no means so generally familiar as it shouW be. The United States Department of Agriculture has recently issued a bulletin on Ctii'bon, Bluuliihide an an, Inaeetiel'le, (Farmern' , No. , by W. E. Hinds,) which should be in the hands of all who contem- plate employing this valuable substance. The bulletin describes the properties of the liquid and its vapour -with the effects it produces on human beings if inhaled. Evidently carbon bisulphide can be confi- dently recommendefl as a general insecticide and can be handled with perfect safety if the user is familiar with the i)roperties of the liquid and its vapour. Carbon bisulphide is said to cost from 35 cents j)er pound retail to 10 cents or less a pound if bought ill 5011). cans or drums. Its in agriculture in America antl Eiux)po appear to have been very varied. It has a special value against underground pests, such as the J'liylloxeju of griii>Q vines: the liquid injected into the soil vapoin-ises, and the vapour while proving fatal to the insect does not remain long enough in the ground to prove injurious to tiie j)lants.
