usually better insecticides than they are fun^cides^ The tabu- 

 lar results are given on page 34. 



Five Prepared Bordeaux Mixtures were found on sale in the 

 State or else registered in 1914. The tabular results are given 

 on page 35. There is apparently a decreasing demand for this 

 class of materials, which are far more expensive than home- 

 made bordeaux mixture and if used in accordance with direc- 

 tions are not as effective. If used in sufficient quantity so as 

 to be comparabl'e with the home-made bordeaux mixture they 

 are effective but are expensive. 



Lime Sulphur Solutions. It requires some special apparatus 

 for the home preparation of lime-sulphur solution, which brings 

 it about that most of the small orchardists prefer to buy a 

 ready-made lime-sulphur solution than to make one themselves. 

 So far as these goods have been examined they have been found 

 to be in accord with their guarantees and in experimental work 

 they have been found to be practically as effective, using the 

 same strength, as though they were home made. The tabular 

 report is given on page 35. 



Powdered Hellebore and Insect Pozvders. A few samples 

 were obtained of this class of goods in 1914 out of the number 

 of brands registered. The results are given on page 36. The 

 value of powdered hellebore and insect powder depends not 

 merely upon their purity but upon their freshness. It will be 

 noted that one sample of powdered hellebore was found to be 

 adulterated. The dalmation powders were practically not at all 

 sampled in 1914. 



Plant Lice Insecticides. Commercial articles for the control 

 of plant lice consist of solutions of tobacco, kerosene and other 

 emulsions and soaps for producing emulsions. The results of 

 the examjination are given on page 37. 



Potato Scab and Oat Smut Preventives. These consist of 

 formaldehyde, and practically every farmer buys this direct 

 under this particular name from a local druggist or dealer in 

 agricultural seeds. The solutions specially registered are 4a 

 per cent solutions of commercial formaldehyde in water. The 

 analyses are given on page 37. 



Dog and Poultry Lice Insecticides. Under this general classi- 

 fication are included a large list of various materials that are 

 sold for the purpose of relieving dogs from fleas, and poultry
