As in previous years, the Bureau of Chemistry has been called upon during the past fiscal year to make a number of analytical and other investigations for other Bureaus and Divisions of the Department and for other branches of the Government. Some' of these investigations are of such a character that they are referred to the special laboratory appropriate in each case. Many, however, have been of such a character as not to fall within the lines of work of any of the special laboratories, and have been investigated by or under the direction of the assistant chief of the Bureau. As a noteworthy example, there may be cited from the work of the past fiscal year investigations undertaken at the request of the Division of Entomology, to ascertain the extent of the danger from fire and explosion attending the use of carbon disulphide as an insecticide. The results of this work have been published in Farmers' Bulletin No. 145.
