toughened by the weather and are not so attractive to the grub. Imme- 

 diately after this operation, a good handful of the following compost should 

 be applied directly aronnd the root and vine : Take equal parts of salt, 

 quick-lime and hen- manure ; place the lime on the floor first, and throw 

 on water enough to thoroughly slack it ; immediately spread the salt on 

 top, following with the hen-manure. When the lime is well slacked, mix 

 the whole thoroughly, and in a couple of weeks it will be ready for use, as 

 above. Do not hill up the hops until the latter part of July or first of, 

 August, and the yard will not suffer any from grubs, but will remain clean 

 and free from weeds the remainder of the season. When yards are hilled 

 earlier than stated above, the grub sometimes works in them more than in 

 late hilled ones. 



To return to the skunks. They seem to have acquired the digging-out 

 process to perfection — far better than the hop grower — as they are able to 

 dig around the hills without the least injury to the vines. In Juneau 

 county, Wisconsin, this little fellow — with an appetite for juicy grubs only 

 equalled in degree by the pungency of his perfume — is the only positive 

 remedy, as he works about the hop-hills or roots, cleaning out the worms 

 in a few nights. One grower says : "I have seen ten acres where not a 

 dozen hills would escape their little noses." 



It is worthy of note that in a majority of cases the growers report the 

 borer as the most injurious insect in the hop yard, not excepting the 

 hop-aphis. 



LEAF-MINING ANTHOMYID^. 



BY J. A. LINTNER, ALBANY, N. Y. 



Among our American species of Anthomyida^, none have hitherto 

 been known as leaf-miners. Several are depredators on the roots of gar- 

 den vegetables, as indicated by the specific names of Anthomyia cepanwi, 

 A. brassicce and A. raphaiii (the onion fly, cabbage fly and radish fly) ; 

 some occur in excrementa, and one, a few years ago, was discovered as 

 preying upon the eggs of the Rocky Mountain locust. During last year 

 and the preceding a species (A. betce) which had been almost unknown 

 since its publication in i860, has been seriously damaging the leaves of 

 beets, in England, by mining them in tortuous channels and large blotches,
