THIRD ANNUAL MEETING. 215 



The question of the part which is taken by professional scientists in connec- 

 tion with the enforcement of inspection laws was discussed, and the following 

 resolution adopted : 



"Resolved, That in the opinion of the American Association of Horticultural 

 Inspectors the specialists employed under the crop-pest laws of the several 

 States ought not to be required to attend to the details of prosecution, either 

 civil or criminal, which may arise through violation of these laws." 



The third question — " To what protection is a nurseryman entitled as against 

 scale infested surroundings?" — was discussed by Messrs. Symons, Alwood, 

 Smith, Britton, Weed, Norton, Scott, Wilcox, Summers, and Piper. 



The trend of the discussion was that it is hardly feasible to attempt to keep 

 nursery stock free from scale with infested surroundings, but that the authori- 

 ties in charge of the suppression of these insects should protect the nurserymen 

 as much as possible against infested surroundings, and in some States the prac- 

 tice has been to commence cleaning up infested orchards and premises around 

 nurseries. It was thought that while it is necessary that nursery premises 

 f should be kept more clean than others the nurserymen deserve protection from 

 infestation from adjoining premises. 



Adjournment. 



The next session met at 9.15 a. m., Wednesday, 



Question 4 — " What is the status of fumigation in justifying the sale of 

 nursery stock exposed to infestation?" — was discussed by Messrs. Engel, Brit- 

 ton, Mackintosh, Norton, Webb, Summers, Smith, Atwood, Burgess, Surface, 

 Rumsey, Johnson, Symons, Weed, and Felt. 



It was the expression of the members that fumigation was the best safeguard 

 we now have against infestation, but many thought an inspection by which 

 visibly infested trees would be thrown out was advisable, since fumigation can 

 not always be made absolutely effective. Special care should be taken that 

 the materials used in fumigation are of the proper strength, and if possible 

 they should be used under the supervision of competent authority. 



The question of the effectiveness of fumigation against woolly aphis was 

 discussed, with the decision that it was a perfect safeguard except against 

 the eggs of this insect, which are not killed by it. 



The question of what should be done in infested orchards was discussed, 

 showing a wide range of recent experience in the East with the lime and sulphur 

 wash which is now being much recommended as the most effective treatment for 

 scale in orchards in the East. 



The effectiveness of this treatment against the leaf curl and other fungus 

 diseases was brought out. 



A motion was carried to continue the organization under the following offi- 

 cers : S. A. Forbes, chairman ; John B. Smith, vice-chairman, and J. B. S. Norton, 

 secretary. 



Adjournment. 



The next session was held at 4 p. m. Various questions concerning San Jose 

 scale, and the use of the lime and sulphur wash were discussed by Messrs. Wash- 

 burn, Weed, Surface, Scott, Piper, Smith, Summers, Felt, and Alwood. 



A motion was carried that the association advise the use of the formula 1-2-4 

 in fumigating with hydrocyanic-acid gas. 



The following resolutions were adopted : 



" Whereas during recent years the dissemination of certain species of insects 

 and fungi on nursery stock has resulted in the rapid spread of injurious insect 

 pests and plant diseases ; and 



" Whereas many of the States of the United States and the Dominion of
