In summarizing these reports it will be necessary only to call attention to such practices and experiences in Canada as are at variance with those already reported from the northern states. For example, in response to the question, "What species are you planting experimentally or commercially?" we find, surprisingly, that Persian walnuts displace black walnuts from first place, at least in these reports, and that filberts and heartnuts come next. Then come black walnuts, butternuts, hickories, hazels, Chinese chestnuts, persimmons, Jap walnuts, almonds and a scattering of other species. Leading native wild trees are, first hazels, then black walnuts, hickories and butternuts. Winter climate is widely varied, being temperate along Puget Sound and close to the southern tier of the Great Lakes, but subject to great extremes in the prairie provinces. Lower winter temperatures in these provinces average from zero to 45 deg. below, while the lowest recorded is reported to have been 62 deg. below. It is evident that Canadians have widely variable problems, in spite of which three Canadians, exactly the number reported from the northern states, tell us that the sale of nuts is an important item in their annual incomes. It looks as though, in comparison, northern U. S. growers could do better. With an average frost-free season of less than five months (from May 7 to Oct. 2), Canadians do this. The normal dates of latest spring frosts average from April 20 to May 24, and of earliest fall frosts, from Sept. 10 to Oct. 12. Extremes at either end often shorten the season somewhat. Soil conditions are generally good, with plenty of loam and sandy-loam, half lime, half acid; but drought is serious in places, necessitating irrigation. One wonders whether, if more of us were pushed to it, we might not find irrigation so profitable that we would never again be without it. Cultural and soil corrective practices are, in general, similar to those previously reported. Less trouble is experienced from rodents--mice, rabbits, squirrels--but more from deer. Wrapping the trunks of young trees is more generally practiced than with us of more southern latitudes, and disk cultivation is more generally favored. In reply to the question, "What was your one greatest source of success?", the answers include, pollination by hand, the use of good trees, disking, planting hardy seed, and budding Persians on black walnut stocks. Failures were due mostly to the inevitable causes, cold, drought, weak growth. Alkaline soil is mentioned in one report as a chief difficulty. Bud worms, June beetle, leaf hoppers and walnut caterpillars are also enemies, but Canada seems free from some of the other pests that have invaded the United States.
