In. this way everj' variety is pretty thoroughly examined, and when 

 any San Jose scale is found a tree-to-tree inspection is made of that 

 entire variety or block. An outline of the course pursued when San 

 Jose scale was found in small numbers in one of our large nurseries 

 last season will illustrate our usual method of handling infestation. 



In the first place, all centers of infestation were located carefully, 

 and the trees within about twenty feet in every direction cut down 

 and burned. These infestations were located by making a tree-to-tree 

 inspection of each block in which any scale at all had been detected. 

 About six weeks after the first inspection these blocks were again given 

 a tree-to-tree inspection, and all infested and adjoining trees burned. 

 Then, when shipping time arrived, the nurserymen were instructed to 

 fumigate everything sent out, and one of our inspectors detailed to 

 superintend the entire fumigation. The nurserymen were requested 

 to do all digging at as nearh- one time as possible, in order that our 

 inspector would not have to spend too long a time at one place. The 

 trees were examined by our inspector as they went into the fumigat- 

 ing house (built according to our directions), and any infested trees 

 found thrown out. Fumigation with 98 per cent. KCN and C. P. 

 sulphuric acid was insisted upon. In this manner we believe that 

 the interests of those purchasing these trees are as thoroughly pro- 

 tected as is possible. 



In addition to the regular inspection of nurseries our inspectors 

 are instructed to inspect all orchards or susceptible trees within three 

 quarters of a mile of a nursery, and where such places are found in- 

 fested proper treatment is enforced. 



All inspections are made by the entomologist of the State Crop Pest 

 Commission or by his regular assistant entomologists. 



Nurserj^meu are required to throw out all trees infested with woolly 

 aphis, nematode root knot, crown gall, hairy root disease, etc. 



Through the kindness of Dr. L. 0. Howard and the chief of the 

 Bureau of Horticulture of the New York Department of Agriculture, 

 we have been kept notified of all foreign, shipments to this state via 

 the Port of New York, by which way most of our foreign shipments ar- 

 rive. ]\Iost of these shipments are of bay trees (Laiirus nohilis) and 

 some other ornamental plants from Belgium to the New Orleans flor- 

 ists, and, although we have examined several thousand such plants, no 

 trace of gypsy or brown-tail moths has been discovered. We have 

 sent out circular letters to the nurserymen, requesting notification of 

 the placing of all orders for foreign plants, and they have been very 

 prompt in responding.
