Fumigation investigations in California . dcart of the samegenera] description as that in use l>y the San Bernardino County outfits lias been adopted. The handle of the carl and the arrange-ment of the lights have been improved upon: while the use of faucetsin drawing off the acid and water is also an improvement. One of 60 FUMIGATION INVESTIGATIONS IN CALIFORNIA. the carts equipped for use is shown in figure 23. As purchased thecart bed consists of a plain box fitted with a two-shaft handle. Thishandle is removed, and is replaced by a tongue having an enlarged link-shaped iron about a foot long, firmly attached at the end. Thislink-shaped handle is very convenient in field work. The scales forweighing the chemicals are placed on a platform above the centerof the box. The cyanid is contained in a tin-lined box in the rearhalf of the cart, while the acid and water are placed in the front 10-gallon keg firmly attached in a horizontal position to the bedof the cart i- a very convenient receptacle for the water. A galva-. Fig. 23.—Cart used with the improved system of fumigation. (Original.) nized-iron basin like that shown above the keg in figure 23, having anopening at the bottom fitting into the bung of the keg. make- a verysatisfactory funnel for filling the keg. The acid may be held in anearthenware jar or a lead-lined tank, with cover firmly attached toprevent slopping. By way of a cover for the earthenware jar we have used a lead-lined lid. which fits tightly within the top (fig. 24). At the center ofthis lid is an opening about 6 inches in diameter, around the circum-ference of which is attached a leaden tube which extend- downwardseveral inches and prevents the slopping of acid through the lead-lined cover lit- into the top of this tube. This opening in theer is for use in filling the jar. AN [MPROVED SYSTEM. 61
