condition and by the continuance of vigorous combative meas- 

 ures will even lessen the disturbances of the gypsy moth in 

 their nurseries. Not only the nursery stock but the surround-

During the year a limited quarantine has been placed by the 

 State Nursery Inspector against the importation of currants and 

 gooseberries. The object of this quarantine is not to discourage 

 the growing of this valuable fruit in the State, — in fact we 

 would encourage its production in certain localities, — but we 

 do at this time wish to exclude the species of Ribes from those 

 sections where eradication of these plants is being undertaken 

 to prevent the spread of the white pine blister rust. Nursery- 

 men and others wishing to import currants or gooseberries may 

 apply to the State Nursery Inspector for a permit, which will be 

 granted on agreement of the importer not to ship these bushes 

 to the prohibited towns. 



Requirements of the nursery inspection regulations of the 

 States change from time to time, and nurserymen are advised 

 of such changes whenever possible. It should be noted that 

 the State and Federal restrictions now prohibit the movement 

 of five-leaved pine to all States except Connecticut. 



The inspection of foreign nursery stock, while conducted with 

 the same vigilance as in previous years, required much less 

 time than usual owing to the very material decrease in the 

 number of shipments received. The time gained here was 

 spent to good advantage in the inspection of interstate ship- 

 ments, which were in most cases found to be of good quality 

 and clean. During the past year only 95 shipments, consisting 

 of 559 cases, were received from foreign countries, as compared 

 with the 219 shipments of 1,067 cases in 1917 and 594 ship- 

 ments of 5,181 cases in 1916. The following table shows the 

 origin of this stock: —
