Excerpt from Cotton Boll Weevil Control by the Use of Poison
The best way to make sure of having the proper grade of calcium arsenate is to send a sample to the Delta Laboratory at Tallulah, La., for free analysis. This analytical service was started by the United States Department of Agriculture last season and if possible will be continued until the quality of calcium arsenate on the market becomes more uniform. Every cotton planter who purchases calcium arsenate for this work is invited to send in samples and he will be given an immediate report as to whether or not the material is satisfactory for use in cotton dusting. For this purpose it is advisable to take at least two or three samples from as many different packages. Prob ably the best plan is to sample 1 package in every 10 purchased. Half-pound samples should be taken from each and packed separ ately. The complete record of each sample should be packed with that sample, giving its full history, including name of manufacturer, when purchased, size and type of package, condition of material, analysis claimed by manufacturer, etc.
