Dr. MacDaniels: "I realize that there are more trees which are starving to death than are being overfed." Silvis: "Do you recommend that freshly cut hay be used as mulch?" Van Haarlem: "Any crop refuse can be used as mulch. Anything that will rot down. The pH of the soil should be 6.2 to 6.5." O'Rourke: "Would you use clean cultivation for the first year?" Van Haarlem: "There is nothing against it. We use sod mulch at Vineland. The reason that our growers are not growing nut plantations is that good land, that is good soil, sells for $1,000 per acre. Nut trees grown on poor land, cheap land, do not produce." McCollum: "I am surprised that rain would not go through loose straw and will go through old straw. Where does the rain go when it falls on the loose straw?" Van Haarlem: "It is absorbed before it gets through the straw. Dry mulch should be 18 inches deep." Member: "How would you prevent erosion on rolling land?" Van Haarlem: "Plant on the contour." Dr. Crane: "How often do you renew mulch under trees?" Van Haarlem: "After first application additional may be needed but after that enough is grown under trees which when cut and raked will suffice." Report from Southern Ontario ALEX TROUP, Jordan Station, Ontario Here in southern Ontario we find that most of the northern nuts do well in most seasons. Among black walnuts the Thomas, Ohio, and many others do well. The Thomas does not always fill. The Ohio seems to be the favorite among Persian (English) walnuts. Franquette, Broadview and a few others are satisfactory but sometimes do not fill well. Of Japanese heartnut walnuts nearly all do well. The Mitchell, Stranger, Bates and others are satisfactory. All the shagbarks and shellbarks are doing well, although only the young shagbarks are bearing, and then only lightly. Chestnuts have done well at times but some trees have been killed by the blight. We have Japanese, Chinese and some other seedlings. They are sometimes winter injured. Filberts are satisfactory and usually bear well. We have Barcelona, Du Chilly, Troup, White Aveline, Italian Red, Kentish Cob, Daviana, Mosier, Guy Smith, Nonpariel and Brixnut. The Barcelona drops nearly free of the husk and is a fine nut. Most are of this variety. We do not have hazels. Pecans will grow and bear but do not fill. Nut Trees Hardy at Aldershot, Ontario, Canada O. FILMAN, Aldershot During the past nine or ten years I have planted a few trees of some of the better known varieties of northern nut species, some of them chosen from the lists of promising selections in the annual reports of the Northern Nut Growers Association, some on the recommendation of reliable nut nurserymen. These trees have been planted here and there in various locations where space permitted on a small fruit and vegetable farm, not in orchard form nor in a solid nut tree planting.
