the orchard as "well, properly carried out, can be depended upon to bring 

 to light the worst cases at least of infestation by the San Jos6 scale and 

 other insects and plant diseases of a seriously injurious nature. Judg- 

 ing from our observations one of the chief benefits which has thus far re- 

 sulted from nursery stock inspection in this state, is to make the growers 

 and dealers more careful as to the condition of the stock sent out. It is 

 probably not overestimating the value of nursery and orchard inspection 

 to say that, properly carried out, it will be a constant stimulus to the 

 production of clean, healthy stock, and will result in effectually holding 

 in check such dreaded pests as the San Jos6 scale. 



THOSE BENEFITED BY INSPECTION. 



If inspection has a tendency to bring a better class of nursery stock on 

 the market, then it is evident that not only the nurserymen, but all inter- 

 ested directly and indirectly, in the growing of trees, shrubs and vines are 

 more or less benefited thereby. Where the inspection is extended to the 

 orchard the benefit is much greater. Farmers should keep this in mind 

 and note carefully the condition of the trees when they come from the 

 iii.rsery and watch for the development of injurious insects and diseases, 

 lu this way each farmer can be the inspector for his own premises. 

 TSTutserymen have usuallj' considered inspection something of an annoy- 

 ance, but cheerfully take the necessary steps for their own benefit and to 

 satisfy- their customers. 



A GROWING DEMAND FOR INSPECTION. 



As previously stated, several states have recently passed inspection 

 laws similar to the Marj'land law. Hence all nurserymen doing business 

 in these states require certificates in order to prevent serious interference 

 with their business. These restrictions to the trade have created a de- 

 mand for nursery stock inspection which is far too great for a station 

 entomologist to meet properh' without aid if he expects to carry on his 

 regular work. We found the demands for this kind of work so heavy 

 during the past season that, in order to prevent a too serious interfer- 

 ence with other duties, it was necessary to restrict our inspection for the 

 most part to Ontario count}- alone. As yet no provision has been made 

 either by state or federal law to meet this urgent demand of a highly 

 important industr}'. 



VARIETIES OF TREES, SHRUBS AND VINES EXAMINED. 



It is not necessary to give a list here of the varieties of trees, shrubs 

 and vines examined. It is safe to say that practically all the varieties of 

 plants grown as nursery stock in western New York, both in the field 

 and under glass, were examined on different occasions. By far the 

 greater part of the stock inspected, however, consisted of the various 

 varieties of fruit trees, 



VARIETIES OF TREES MOST COMMONLY INFESTED. 



These were the apple, peach and pear trees. The apple and pear trees 

 were most commonly infested with the woolly aphis, and this pest was 

 most often found on the Ben Davis and Yellow Transparent apples and 

 upon the standard pears. In most cases of infested pear trees, the blocks
