N(.> 6. DEPARTMENT OF AGRICULTURE. 123 



The above table shows that there are two thousand three hundred 

 and tift^-seveu acres devoted to the industry alone in Pennsylvania. 

 Twenty of these nurseries, comprising eleven hundred and eighty-five 

 and three-quarter acres, are reported to be in very good condition; 

 sixty nurseries of nine hundred and fifty-six and three quarter acres, 

 are in good condition; thirty-three, aggregating one hundred and six 

 and one-half acres, are in fair condition, and eighteen, comprising one 

 liuudred and nine acres, are in indillerent and poor condition. Of the 

 latter, thirteen nurseries of seventy-five, and one-quarter acres, are 

 reported to be poorly kept, thus showing a very small percentage of 

 the total acreage to be in poor condition. 



Many of the nurseries are equi[)ped with fumigating houses, while 

 others contemplate the erection of similar plants. Hydrocyanic acid 

 gas is used in fumigation. 



The Departments of Agriculture of other States having a nursery 

 inspection law, are acting in co-operation with this Department in 

 this matter, and have been of material assistance in carefully watch- 

 ing shipments fro'm this State, of diseased nursery stock, and stock 

 shipped without the certificate of inspection attached thereto. 



The oflrtce work of the Division has been quite extensive. Hun- 

 dreds of letters have been received and answered, bulletins sent out. 

 and inquiries relating to various injurious insects and tree diseases 

 have been addressed to persons pertaining to the work of this Divi- 

 sion. The sending out of notices relating to nursery inspection to 

 transportation companies, the filing of all reports and the issuing of 

 (ertificates, have also taken up considerable of our time. 



To make mention, briefly, of the many injurious insects sent to the 

 Division for determination and remedial measures, the tent cater- 

 pillar was the most prominent. It was abundant in all sections of 

 the State, and was found on both shade and fruit trees. Special at- 

 tention was given each and every inquiry, and it is to be hoped that 

 the injury caused by this insect will be greatly diminished the coming 

 year. 



The Angoumois grain moth, was again troublesome in the eastern 

 section, although it seems to have been less destructive than last 

 year, owing, no doubt to the information given in treating the subject 

 in full, aiid the general dissemiiiation by this Division during the 

 former troublesome period of this enemy to our grain crops. 



Very respectfully, 



BENJAMIN F. MaeCARTNEY, 



Economic Zoologist.
