year or two, been imported on nursery 

 stock into a good many of our States 

 and into the Province of Ontario, Can- 

 ada. Earnest effort has been made to 

 stamp it out at these points of introduc- 

 tion, and it is hoped that this work has 

 been successful. If this disease becomes 

 established in this country it will result 

 in enormous losses in our pine forests. 



Both of these diseases are examples of 

 dangers which can be prevented only by 

 an absolute quarantining of the infested 

 foreign districts, so far as importations 

 therefrom to this country of these par- 

 ticular products are concerned. In other 

 words, these diseases are often not dis- 

 coverable by inspection, and cannot be 

 destroyed by fumigation. The pine dis- 

 ease may be present in the pine for two 

 or three years before giving any visible 

 demonstration. The potato-tuber disease 

 may be in imported potatoes and simi- 

 larly escape detection. 



EFFORTS TO SECURE LEGISLATION 



The necessity for a national quaran- 

 tine against foreign insect pests and plant 

 diseases has long been recognized, and 

 during the last 14 years, especially, a 

 strong continued effort has been made to 

 secure such legislation. This effort has 

 been blocked very largely by a small body 

 of importing nurserymen, who, careless 

 of the consequences to the country at 

 large, feared some slight check on free- 

 dom of their operations. The main body 

 of nurserymen have interests identical 

 with the fruit-growers and are in favor 

 of protective legislation, and The Na- 

 tional Nurseryman, the principal organ 

 of the nursery trade of this country, has 

 taken positive stand in support of such 

 legislation. 



The entire value of the imported nurs- 

 ery stock, as declared at customs, which 

 is thus menacing the safety of this coun- 

 try is about $350,000 annually — scarcely 

 more than the government is now appro- 

 priating to assist in the effort at the 

 control of the gypsy moth alone in New 

 England. 



Some of this imported stock is of 

 ornamentals neither new nor peculiar, 

 and is merely brought in because of 

 cheaper production abroad. A large per- 

 centage of it is seedling apple, pear, 



* These moths emerge early in July, are strong fliers, and have spread from the original 

 point of infestation near Boston, northward and eastward, over much of New England, for- 

 tunately the prevailing winds are to the northeast during this season, and their spread to the 

 south and west has been comparatively limited.
