Reeommemdations. 



The net result of all the work done bv or throusrh the officei and 

 in t)ic orcliards under all sorts of conditions by all sorts of men is 

 that confidence in the mixture as a scale^killer is justified. But to 

 obtain reliable results, the 1 to 20 mixture is too weak. It contains 

 only about 3V> per cent, of actual oil, and this will not be sufficient 

 to penetrate a thick layer of scales; 1 to 15 will be much moTc 

 effective, and even that should be very thoroughly applied. Fur- 

 ther, because of the practical difficulty of reaching all parts of 

 large trees at any one application, two sprayings are advised, one 

 in fall and the other in spring. There need be no fear of injury 

 from even the most thorough applications at this strength. 



TARGET BRAND. 



"Target Brand" scale destroyer is a petroleum combination 

 made by the American Horticultural Distributing Company, at 

 Martinsl)urg, W. Va. I visited their plant in the late fall of 1905, 

 and by the courtesy of the president of the company, Mr. John W. 

 Stewart, and the then chemist. Dr. P. Karutz. I had an oppor- 

 tunity to examine the outfit for making and to learn the composi- 

 tion of some of the insecticides made by the company. In response 

 to my request, the photographs illustrating this report w^ere sent 

 me and also the matter in quotation marks in this account. 



The plant consists of a three-story building fifty by one hundred 

 and lifty feet, in which the actual manufacturing is done, and a 

 one^story building fifty by one hundred, which contains storage 

 rooms for the mineral and vegetable oils, as well as engine and 

 boiler-room. The lower floor of the larger building is devoted 

 largely to the shipping department; the middle floor contains 

 laboratory, salesroom, shipping and finishing di^partments, while 

 the distilling, mixing and other manufacturing is done on the 

 third floor. A siding from the Cumberland Valley railroad nins 

 directly to the huilding and facilitates llie receipt of sujiplies and 

 delivery of products.
