The National Nut Growers' Association has done no greater service to the pecan industry than that which they have rendered in protecting the public from fraudulent agents and nurserymen. Happy is the nurseryman whose reputation for square dealing merits the trust and confidence of tree-planters throughout the country. COST OF NURSERY STOCK. At present, the prices quoted for one and two year old stock of standard varieties varies from 75 cents to $2.50 per tree, in small numbers, with considerable reduction for trees in lots of one hundred or one thousand. It is not improbable that these prices may be somewhat reduced within the next decade, as greater efficiency is gained in propagating. DETECTING BOGUS TREES. How may budded or grafted trees be distinguished from ordinary seedlings or from "doctored" seedling trees? Many people have purchased seedling trees at a dollar or so per tree, under the supposition that they were budded or grafted stock. It is well to know something of the distinctions between them. [Illustration: FIG. 27. External and Longitudinal Interior View of Bud Union.] If the trunks are straight and smooth, with bark uniform in appearance throughout, the trees have not been budded or grafted, unless the point of union is at the ground, and the trees having been grafted, and a terminal bud on graft has grown. If the young trees have been budded, the trunks will not be straight; a bend will be seen at the point where the bud was inserted (see Fig. 27), and the scars of the union of the veneer-shield or annular bud and the point at which the stock was cut off will be distinctly noticeable. The bark above the point of union on the grafted or budded stocks will be different from that below. There is something characteristic about the color and appearance and the number, size and shape of the lenticles of each variety of pecan, and while it is impossible to describe this difference in appearance (it can only be learned after a large amount of experience and observation), yet the very striking difference between the seedling stock and the wood of the variety worked upon, will serve as a useful index to the genuineness of the trees in question. If the trees have been grafted instead of budded, the same statement will be true of the appearance of the bark. But the tree will be more nearly or quite straight, and the marks and scars at the point of union will be different. If the trees have been propagated by whip-grafting, the scar will be shaped like the letter N, the scar on young trees coming nearly or quite the whole distance across the stock. If the trunk of a whip-grafted tree is split through the point of union, the N-shaped mark in the form of a dark line may be distinctly made out, as shown in the illustration. In trees propagated by cleft-grafting, the union scar will be long, slim and V-shaped. [Illustration: FIG. 28. External and Longitudinal Interior View of Whip-graft Union.]
