connected with the application of an improperly prepared emulsion. 

 The accompanying illustration shows sprayer with attachment. 

 The latter consists of a separate tank filled with the kerosene and 

 attached to the main tank, but 

 readily detachable. Any pro- 

 portion of kerosene and water 

 can be pumped from the nozzle 

 by simply turning the stopcocks. 

 The kerosene and water are so 

 thoroughly mixed in the act of 

 pumping that the kerosene is as 

 harmless to foliage as in an 

 emulsion of the same strength. 

 This attachment can also 

 be used for many purposes other 

 than the mechanical mixture of 

 kerosene and water. In many 

 cases it may be best to dilute 

 fungicide only when applied to 

 the foliage in the act of pumping. 

 For this purpose the attachment 

 will also prove useful. Of course 

 when copper or other corrosive 

 compounds are used in this 

 manner, the small tank should 

 be made of brass instead of tin.

Gypsine. — The new insecticide gypsine, so called because 

 first used for the gypsy moth in Massachusetts, is an arsenate of 

 lead, and claimed to be fully as effective as Paris green, and su- 

 perior to it in many respects. It has the advantage of being 

 readily seen on the leaves, so that one can tell at a glance which 

 leaves have and which have not been sprayed. Being lighter 

 than Paris green it does not settle so quickly, and as a result can 

 be distributed more evenly over the foliage. It does no harm to 

 the foliage, even if used in much greater strength than the form- 

 ula directs, so long as the right proportion of the two ingredi- 

 ents is maintained. There should be an excess of acetate of lead. 

 The insecticide is easily prepared by dissolving eleven ounces of 

 acetate of lead and four ounces of arsenate of soda in 150 gal- 

 lons of water. These substances quickly dissolve and form the 

 arsenate of lead. The addition of two quarts of glucose or 

 molasses will tend to glue the poison more firmly to the foliage. 

 The cost of making this mixture is slight. 



Welcome Help — It cannot be denied that we have a great 

 many good friends and helpers among the creatures that walk, 

 creep, and fly. The average gardener, however, is often entirely 

 unaware of how much of his exemption from insects or of his
