Instead of dropping the Blackman plum from nursery catalogues and burn the stock on hand, as suggested by H. E. Van Deman, Pomologist, Agricultural Department, why not use it for stocks for plum or peach? Its remarkable vigor no doubt would make it a desirable stock for peaches. These would be very nearly borer proof, and from experiments made, perhaps " yellows " proof.

H. M. Engle, of Marietta, Pa., one of our most progressive fruit growers, has been experimenting on this line for several years past. He inserted buds, unmistakably infected with yellows into the Blackman, and they came forth perfectly healthy. His experiments are too few and recent to settle the question, but they are of such importance as to warrant others to continue them.

As the Blackman produces little or no fruit, we have to utilize it as a stock, by first working it on other plum stocks. These, if set deep, will soon form roots from the Blackman, and make good plants.

But we now have a promise of a more convenient stock grown from cuttings. Mr. McLendon, of Thomasville, Ga., claims to have grown from cuttings planted 15th last March, stocks from 3 to 8 feet high. He desires to be furnished with the cuttings (he paying the freight) and agrees to deliver all that grow at $5.00 a hundred. The price is too high for general peach budding, but for carrying out experiments it would be endurable. If peaches would thrive on these plum stocks, they would be desirable, even if they were not yellows proof.

The yellows I think would not enter the plum roots, and if so our soil would remain clean. The roots of dead peach trees are so full of the yellows that in spite of all our knowledge of plant foods, nitrogen, potash, phosphoric acid, magnesia, lime, etc, we cannot successfully raise a young orchard among the stumps of an old one.

[ Mr. Hiller's suggestion we regard as well worthy the attention of peach growers. We have for years had not the slightest doubt but that the disease known as the yellows comes primarily from the attack of a fungus, - the mycelium of a species of Agaric, on the roots of the peach. This fungus starts on dead or half-dead wood, and then spreads to the roots that are healthy. In some form, not clear to the writer, it enters the structure of the tree, and possibly originates the minuter fungus organisms found by Prof. Thomas Taylor, and other investigators, in the wood of the diseased tree. In like manner it possibly changes physiological action, so as to account for the lack of mineral elements found by Prof. Penhallow in diseased structure. Be all this as it may, no peach tree shows this disease till after the fungus mycelium has attacked the roots.

Now if it can be shown that this fungus does not care to attack plum roots - and we believe the evidence tends to favor Mr. Hiller's views in this respect - it will pay the peach grower, even at $5 per hundred for the stocks, to have the trees on plum roots. But if we can once get a fair demand for the stock, even though it has to be propagated from cuttings, layers or root cuttings, means will be found to produce them cheaply. A peach tree that is warranted free from attacks of the yellows and will continue in bearing for a quarter of a century, will be well worth ten-fold more than the ordinary tree, with its short life and great risks. - Ed.
