Now we come to the hybrids. This is the parent tree of the Mc- 

 Callister discovered many years ago, probably in the late 80's, by a 

 Mr. Floyd, but the tree belonged to a Mr. McCallister. Mr. Floyd 

 was of Missouri. He took scions south, and six trees, if I am not mis- 

 taken, were grafted on pecan and grown at Washington, Georgia. 

 Later the variety came to the attention of the United States Depart- 

 ment of Agriculture and the name McCallister was definitely fixed. 

 Because of the enormous size of the nuts, the vigor of the parent tree 

 and the fruitfulness, it attracted unusual attention. As a result a 

 great many of the pioneer pecan men of the South developed trees by 

 top-working pecans with the McCallister, but the only instance that 

 has come to our attention in which they were satisfactorily fruitful in 

 the South was in those six trees in Washington, Georgia. But no- 

 where in the South have they filled well. Over in Delaware, at Mil- 

 ford, there are two trees referred to by Mr. Hershey grafted, one on 

 hickory and one on pecan, by a i\Ir. Corso. I saw those two trees the 

 other day. I have seen a few nuts that were filled. The ones I saw 

 were filled much better than the average of what we have seen in the 

 South, or from this parent tree. It may prove to be worth more in 

 the North than in the South. 



It is rather unusual for oversized nuts to be dependable in filling 

 quantity. Many years ago while Mr. Jones was a youngster in 

 Missouri, he found a hybrid hickory in the northeastern corner of the 



state which became known as the Rockville. 



About two weeks ago Dr. Smith wrote to us at Washington asking 

 what we could tell him about the Cedar Rapids, shagbark. Now there 

 are two hickories that have been knoAvn by that name. One is a shag- 

 bark which I am not familiar with. The other is the tree named by 

 Dr. Dennis of Cedar Rapids, which is a sweet bitternut. I have 

 never seen the nuts of this tree. But you notice the fine branches 

 characteristic of the bitternut. 



Now we come to the chestnut. The last word has not been said 

 about the chestnut in the East. We feel that the chestnut will some 

 day come back. That slide of course needs no explanation. It is 

 typical of what we have seen through the chestnut range from the 

 lower New England states down through Pennsylvania to North
