It is, therefore, desired to take stock of this work and to determine, so 

 far as is now possible, a program for the future. 



That there is a large risk in connection with the importation of fruit 

 stocks, and also rose stocks, has "been strikingly demonstrated, particularly 

 during the last two 'seasons. In the case of both of these stocks now permitted 

 unlimited importation, there has been during these years an unusually heavy 

 infestation with the larval nssts of the brown-tail moth and also with the similar 

 but smaller larval nests of the white tree pierid, an insect new to the United 

 States, which may vory possibly prove to be a serious enemy to the horticulture 

 of this country. Most of this infestation has been on French stock and, in 

 response to a second and serious presentation of the case to the French inspection 

 authorities, this Department has been advised that important changes have been 

 made in the inspection service of that country and assurances have been given 

 that every effort will be made to eliminate any future cause for such complaint. 



Rose Stocks . 



As to rose stocks, these, at the tine of tho hearing in 1918, preliminary 

 to the quarantine, were represented by prominent rose gravers of the country as 

 a necessity for the time being at least. Since the promulgation of the quarantine 

 many prominent rose growers and experts have advised the Department that the in- 

 clusion of rose stocks under Eegulation 3 was unnecessary and an error, and that 

 rose stocks could be produced in this country as well as abroad, and that the 

 risk from the entry of this class of importations could be and should be elimin- 

 ated. The Board wants this subject, therefore, discussed and wishes the advice 

 of the rose interests on the matter. 



ther Ornamentals . 



I have already pointed out that the Department believes that Regulation 14 

 will meet tho introduction needs of ornamental plants, both, herbaceous and woody, 

 "but if any such ornamentals can not be produced in this country with the ample 

 provisions made for the entry of propagating stock, it is proper and desirable 

 that such items should be brought up for discussion at this time for inclusion 

 under the conditions of Regulation 3. 



This analysis covers the general subject for your consideration and, as 

 already indicated, the Department hopes to secure from the conference constructive 

 suggestions as to desirable changes which can be made without material increase 

 of the risk of entry of pests.
