In answer to your Texas correspondent in the November number, I would say something about this worthless fruit, but am not able to give him the special information desired as to its actual fruitage. In fact, I have never seen it fruit and join him in the belief that it never does except in very rare cases. The reason of this is, that it is a hybrid between the plum and peach. No doubt this statement will bring out much criticism, but I feel warranted in saying so. During an official trip of observation in Texas this summer I examined a great many trees of the Blackman and in no case did the owner report fruitage. In general appearance the tree resembles the peach fully as much as the plum. The leaves have glands and this never occurs on any species of plum.

I venture to guess that the seedling of Wild Goose that Mr. Stell speaks of is a chance hybrid also. On the grounds of T. V. Munson, at Deni-son, Texas, I saw at least five different seedlings from a wild tree of Prunus Americana which stood near a peach orchard that had somewhat different characteristics, but all plainly showed the effects of hybridization with the peach. Mr. Munson had saved them from a lot of plum seedlings (grown for propagating purposes) especially to examine them with regard to this interesting subject. They have so far failed to bear although they have bloomed one or two years. Mr. Munson first called my attention to the Blackman being a hybrid. Judging from what I have seen and heard of this fruit it seems to be a failure except as a botanical curiosity and should be dropped from the nursery catalogues and the stock on hand burned.

[ Botanists would be glad to know for a certainty that two such distinct genera as the Amygda-lus (peach) and Prunus (the plum) would hybridize. The facts reported certainly favor the belief - but on the other hand we must remember that a genus that gave us the almond, the peach and the nectarine, - all without hybridization, but by the sheer force of natural variation alone, may be capable of quite as much sporting as reported by our correspondents. The same is true of the genus to which the plum belongs. Sterility proves nothing. Hybrids are often abundantly fertile, while many a variation well known to have no relation with hybridity, is as sterile as can possibly be.

Exact experiments in these things would be of great value in scientific pomology, and it will no doubt be one of the labors of the new Department of Pomology to investigate these matters. One with the time to isolate a few flowers, emasculate them, and apply the pollen of the opposite genus, could settle the question in a couple of years. - Ed. G. M].
