Such strips should generally be started on the side opposite the prevailing winds at seeding time, so that the seeds may be blown on to the denuded land. Of course, in the case of oak, beech and similar trees, where the wind has compara- tively little effect on the carrying of the seed, this point is not to be so much insisted on. Group method (Fig. 4G3).—The group method is a system of cutting irregular strips successively on the inside of certain groups. This may be termed a natural method, and for general use, especially in mixed woods, and where the land and tree condi- tions are rather variable, it is much the best. If this system is followed, one can adapt the method of cutting to the different species and to the differ- ent conditions which may be found in the forest. For example, a tamarack swamp, a dry knoll cov- ered with oak, a steep hillside, and level rich rocky land covered with elm, and very often various other conditions, would very likely all be included in almost any forest track of considerable size in the northern states, and each part, for best results, should receive special treatment. Under this plan we can begin with one group or several, and we can start our regeneration in each group perhaps where there is already a good growth of desirable young trees. In fact, this system gives us a chance to begin regeneration where the greatest necessity or the best opportunity for it already exists. The size of the openings will depend, as in the strip method, on the species grown and on the natural conditions of the land. As a rule, the finst open- ings should be one-fourth to one-half acre or more, and the strips ta
