state. The local inspectors have their allotted territory each year in 

 their respective counties. They are thus enabled to visit each indi- 

 vidual orchard and report its condition to the office of the depart- 

 ment. They come in personal contact with the grower and can point 

 out injury caused by any pest or disease and advise him as to 

 treatment. 



Furthermore, by this local inspection a better acquaintance with 

 the conditions in each locality is acquired and we are enabled to give 

 direct attention to direfully neglected cases and cause treatment 

 either by showing to the owners the great necessity of the same or, 

 if necessary, by enforcing the law. 



Moreover, the local inspectors can explain the work of the depart- 

 ment to the orchardists. and show them that our efforts are directed 

 towards helping them in the protection of their trees and the pro- 

 duction of good crops, rather than in seeing the law enforced. 

 Twenty-seven local inspectors worked in Maryland last season. 



Thus the inspection of nurseries and orchards is conducted in 

 Maryland with little or no friction, and the horticulturists as a whole 

 are ever ready to support the work of the department. 



SOME HOST RELATIONS OF TICKS^ 

 By W. A. Hooker. Washingtoi}, D. C. 



In a paper presented at the meeting of the Association of Economic 

 Entomologists last year, the host relations of ticks were briefly con- 

 sidered. At this time I propose to present some additional informa- 

 tion and deductions that have been drawn. I wish to call your atten- 

 tion first to the fact that in Mr. Nathan Banks' "Revision of the 

 Ixodoidea," which was issued in June, we now have a work by means 

 of which the ticks of this country can be readily identified. In this 

 work nine genera, thirty-eight species (one doubtful) and one variety 

 are described from the United States, including Alaska. During the 

 past year three undescribed species, one an Aponomma (a genus hith- 

 erto not known to occur in this country) and Amhlyomma dissimile (a 

 Mexican and Central American species) have been collected within 

 our borders, thus bringing the total up to at least ten genera repre- 

 sented by forty-one species and one variety. Incidentally it should 

 be mentioned that collections of this one variety {Dermacentor par-
