38 THE REPORT OF THE No. 36 



All the spraying mixtures injured the buds and foliage to a slight but rot 

 appreciable extent. In comparing the Gulp orchard with pear trees which had 

 been sprayed with lime-sulphur 1-20, no difference in the amount of " burning " 

 was noticed. 



Spraying for the Nymphs. In order to destroy the nymphs which had 

 escaped the first spray and those which had hatched from the eggs of belated 

 females, a second application was made after the blossoms fell. Black Leaf 40, 

 3/8 pint to 40 gallons, was added to the regular codling moth spray (Lime-sulphur 

 1-40, arsenate of lead 2^ lbs. to 40) and this was applied with great thoroughness. 



This application gave excellent results. When the orchard was examined a 

 few days later only an old psylla was found. The insect increased very slowly in 

 numbers throughout the season and right up to early September its numbers were 

 very insignificant. The foliage was in beautiful condition all season and the 

 trees bore an excellent crop of pears. 



W. F. W. Fisher's Orchard. Part of a large pear orchard at Burlington was: 

 sprayed at the usual time for the " egg spray," with lime-sulphur wash 1-9 and 

 starch 2 lbs. to 40 gallons and the other and smaller part was sprayed with lime- 

 sulphur 1-7. In addition to this all the trees received the post-blossom appli- 

 cation of Black Leaf 40. 



Results. Excellent results were secured — the psylla was reduced to very 

 insignificant proportions, and for the first time in many years caused no damage. 



EVENING SESSION. 



The Evening Meeting was held at 8 p.m. in the Carnegie Library and was well 

 attended by members and others interested. The chair was occupied by the Deputy 

 Minister of Agriculture, Mr. J. H. Grisdale. The Popular Address was given by 

 Mr. C. L. Marlatt, Chairman of the Federal Horticultural Board, Washington, 

 D.C., his subject being "The Federal Plant Quarantine Act" or ""How the 

 United. States is Preventing the Introduction of Foreign Insect Pests and Plant 

 Diseases." The address was highly appreciated and felt to be of special value to 

 Canadian Entomologists, as was pointed out by the President of the Society, 

 Prof. Lawson Caesar, while proposing a vote of thanks. 



THE FEDERAL PLANT QUARANTINE ACT.

fThe following discussion covers the subject in a general way as it was pre- 

 sented extemporaneously.] 



Most of you undoubtedly are familiar with the Federal Plant Quarantine 

 Act and with the general features of its administration through a Federal Horti- 

 cultural Board. This Act was the outcome of a long, hard fight which began 

 twenty years ago as a result of a nation-wide conference called in Washington. 

 This conference included state entomologists and inspectors and secretaries of 

 agriculture and horticulture and other persons interested in plant protection. 

 The need of a federal quarantine which should give protection to the whole United
