root-lice. If, is thus rendered quite certain that, if it once finds its 

 way to the Pacific slope, our Phylloxera may prove a most serious 

 scourge, and it behooves the Californians to endeavor to prevent its 

 introduction. Let them take warning of France ! 



AMERICAN GKAPE- VINES IN FRANCE. 



The fact that some of our American varieties resist the louse has 

 caused an increasing demand for them abroad. The principal varieties 

 sent by ]\Iessrs. Bush & Son are the Cunningham, Herbemont, Taylor 

 and Clinton, which have been found to resist with M. Laliman, as well 

 as here ; and the Norton's Cynthiana and Concord, which Succeed 

 well with us, but have suffered with M. Laliman. 



As some of my foreign correspondents have thought it would be 

 cheapest to order long cuttings, with several eyes, it will be well to 

 state, for their benefit, that few of our American vines root as easily 

 as the European varieties, and it is almost impossible to propagate 

 some of lliem, except by layering. With the exception of Clinton and 

 Taylor, those which propagate easiest by cuttings are, as a rule, the 

 most sensitive to the Phylloxera, while those which are with difficulty 

 so propagated are among the best resistants. This is very much what 

 we should naturally expect: the tougher the wood the tougher the 

 root, causing, in the one instance, ditficult rooting, and in the other 

 better resistance to the suction of the louse. The accompanying list, 

 showing the comparative difficulty with which some of the better- 

 known varieties root from cuttings, and which is based on the experi- 

 ence of Messrs. Bash & Son, will prove of value in this connection : 



1. Hermann (^Esiioalis) — Most difficult of all to i^ropagate ; refiisino; to root even with 



butloui heat. 



2. Nouton's and Cyxthiaxa (^ZJ.sz!.) — In a very favorable season, on well -prepared, 



virgin soil, and with the best care, only a small per centage will root. 



3. Hekbemoxt, Cunningham, Devekkux {JEst.) — From enttings wade early in fall, 



suo)i after the leaves di'op, and under very fiivorable circumstances and con- 

 diriotis of soil, a better per centage than U'om the former will root ; yet they 

 olCen entirely tail. 



4. RcLANDEK, Louisiana, Alvi<:;y {^^st.), and Delaware (Si;:).)— Are less uncertain 



tlian the former, and with skillful treatment, tlnst causing callus, with best of 

 care afterward, good results have been obtained at times. Without such 

 treatment and care, tliese also will not root well from cuttings. 



5. EuMELAN (^Est.?), Creveling, Maxatawney (Lab.) — Root more freely, and with 



proper care may safely be propagated from cuttings. 



6. Hartford Prolific, Telegraph, Ives, Concord, Catawba, Ioxa, Diana {Lab.) 



— iioot easily from cuttings. Being mostly long-jointed, they make better 

 roots and plants from short cuttings (2 to 3 eyes long) than from long canes. 



7. Rogers' Hybrids, as Goethe, Massasoit, "Wilder, Lixdley, Agawam, Merri- 



iiAC, Salem, etc. — All varieties produced by crosses between Labrusca. and 

 Viniferu grow Irom cuttings as easily, at least, as the varieties of either of 

 tliese two species. Arnold's Hybrids, crosses between Clinton and foreign 

 ( Viiiifera) varieties, grow from cuttings even more freely than any others, 

 except — 



8. Clinton and Taylor {Rip.), which grow from cuttings, like willows, almost with- 



out care.
