wo species in size, color, quality, growth, andother characteristics, both of trees and fruits inall variations. But among the second-generation seedlingsraised from these hybrids some fairly good appleswere produced. In form, some almost duplicatedthe Gravenstein itself; very few of them resembledthe true wild crab t>pe, except that nearly all hada certain crablike acidity and lack of flavor. Some of these hybrids are still growing on mySebastopol farm. No one of them gives promiseof being worthy of introduction, but it is not un-likely that something of value may be developedfrom this stock by further hybridizations and se-lections. The wild crab has certain qualities ofhardiness and prolific bearing that might be ofvalue in combination with the fruiting qualitiesof some cultivated variety. This, at all events, isa line of investigation that offers opportunity forfurther tests. Doubtless the most interesting of these hybrid-izing experiments with the apple tree are those in (204)

I have grown numerous seedlings from a crossof the apple and the common quince, Cydoniavulgaris, and also the giant Chinese quince,Cydonia sinensis. This cross was made both waysin both cases. This is a cross between genera. Some of these hybrid seedlings grew quiterapidly. The growth was generally peculiar, beingcompact and stubby, and often with an unhealthyappearance, especially towards the last of theseason. The foliage and bark most often resem-bled the quince. I expected good results from these interestinghybrids, but not one ever produced even a blos-som. The developments were the same in all seed-lings, however the cross was made. After a fewyears they would decline and die, whether graftedon the quince or the apple or growing on theirown roots. Several varieties of apples were also crossedwith the Bartlett an
