This group is outstanding because it grows ra- pidly and with great thriftiness at low elevations, while most other species of eucalj-ptus show a marked preference for the cooler environment of the higher mountains. At present onlv isolated trees of this ' species are growing, but at about 3,000 feet elevation extensive plantations have been established on Los Guineos, Catahna and Alonso soils. Here trees attain 40 to 50 feet in height and 7 inches in diameter in 5' years. Growth is also very ; in the west- em mountains on poor Xipe clay at about feet elevation. Establishment (termination of the seed is 40 to 50 percent. Seeds are sown in flats or concrete beds because the seed- lings are delicate and need protection from the weather and from diseases and insect.^. The soil is soaked with the standard crude carbolic acid emulsion to eli- minate ants which otherwise carry awav the seeds. Smearing a heavy line of creosote at the base of the concrete bed also helps to avoid attack by ants. Beds are kept shaded during and shorth" after germination- Gne or two pounds of seed are sown per 100 sq. ft of bed area. Between 12,000 and 16,000 seedlings are obtained per pound of seed. Lifting seedlings for transplanting to nursery beds starts after about 50 days, but smaller seedlings can be held for some time afterwards, to be lifted gradually as they reach the proper size. The best size for transplanting to nursery beds was found to be between 2 and 4 inches. A survival of 90% or better is obtained when transplanting to nursery beds. Seed- lings should be spaced at least 3x6 inches in the riursery beds. The amount of cull stock increases sharply when closer spacing is used. The seedlings are ready for lifting after 2 mont
