The _proximate_ success of my grafting is all that I can desire, although, of course, it is as yet too early in the year to know what the _ultimate_ success will be. I mean that, although I cannot yet tell whether the tissue of one variety is affecting that of the other, I have obtained intimate adhesion in the great majority of experiments. Potatoes, however, are an exception, for at first I began with a method which I thought very cunning, and which I still think would have been successful but for one little oversight. The method was to punch out the eyes with an electroplated cork-borer, and replace them in a flat-bottomed hole of a slightly smaller size made with another instrument in the other tuber. The fit, of course, was always perfect; but what I went wrong in was not having the cork-borers made of the best steel; for after I got about one hundred potatoes planted out, I found that the inserted plugs did not adhere. I therefore tried some sections with an exceedingly sharp knife that surgeons use for amputating, and the surfaces cut with this always adhered under pressure. The knife, however, must be set up in a guide, in order to get the surfaces perfectly flat. Next year I shall get cork-borers made of the same steel as this knife is made of, and then hope to turn out graft-hybrids by the score. Even this year, however, a great many of my potatoes are coming up, so I hope that some of the eyes may have struck. I think it is desirable to get some easy way of experimenting with potatoes (such as the cork-boring plan), and one independent of delicacy in manipulation, for then everybody could verify the results for himself, and not, as now, look with suspicion upon the success of other people. With beans I get very good adhesion of the young shoots, but the parts which grow after the operation always continue separate. In some cases I am trying a succession of operations as the plant grows. With beetroots and mangold-wurzel of all varieties, adhesion is certain to occur with my method of getting up great pressure by allowing the plants to grow for a few days inside the binding. I have therefore made grafts of all ages, beginning with roots only an inch or two long and as thin as threads. The other vegetables also are doing well, but with flowers I have had no success. The vine-cuttings were too young to do anything with this year, but I hear from my cousin, who has charge of them, that they are doing well. They certainly have very extraordinary leaves.
