stocking at the end of the third year compared to 1,550 seedlings and 50 percent respectively for covered seed. Another test made in Ontario showed good stocking ( 77 percent) at the end of 4 years from both fall- and spring-sown jack pine which had been seeded on screened spots in a burn. Un- screened spots, on the other hand, were failures (Leslie, 1953). Several attempts have been made to seed-spot jack pine on land that had been previously disked or furrowed. One test on an area of disked soil on the Chippewa National Forest failed the second year, likely because of the re-invasion of grass. Also a failure were trials in Manitoba of seed spotted in the bottom of furrows in June and November 1952 (Cayford, 1959). On the other hand, seed spotting after disking in jack pine clearcuttings showed much better results. Of four trials, one turned out poorly, but the other three showed 900 to 1,600 trees per acre with 45 to 60 percent stocking 7 to 9 years after seeding (Cay- ford, 1959). Seed spotting on unprepared sites has generally been ineffective. Two tests made on the Superior in a jack pine clearcutting showed only a poor stocking at the end of 3 years, but a test in simi- larly cut jack pine in eastern Ontario had excellent results (Logan, 1951b). Trials made on both open sand plains and under adjacent poor-site aspen, also in eastern Ontario, failed (Horton and Mc- Cormack, 1961), as did six of eight Vi-acre plots so seeded on open jack pine land in Manitoba in the late 1920s. Of the remaining two plots, one plot .3 to 6 years after seeding had a fair stand while the other was well stocked (Cayford, 1959). Seeding With Handtools At Aurora, a 1-acre tract burned in the fire of 1936, was seeded in 1937 with an Efco rake. This tool, resembling a potato hook, has a hollow handle containing the seed. After a spot is prepared with the rake, a few seeds are released and worked into the soil. Germination was good and survival high, the plot showing 2,200 seedlings per acre at the end
