If we begin with a group of young growth alieady on the ground, our plan is to remove gradually the old tiees standing over them when no longer required for shade, and then to cut away the adjoining old growth and enlarge the opening in successive nanow bands around the young growth. When the fiist band has seeded itself satisfactorily, and the young growth has come to requue more light (which may take several years), we remove another band around it, and thus the regeneration progresses. Where no young growth already exists, of course the first opening ib made to afford a start, and afterwards the enlargement follows as occasion requires. SIZE OF OPENINGS. The size of the openings and tne rapidity with which they should be enlarged vary, of course, with local conditions and the species which is to be favored, the light-needing species requiring larger openings and quicker light additions than the shade enduring. It is difficult to give any. Old timber 3d 2d 1st cutting 0d Tig 40 —Appeiranc* of le^t nci iti m 1>> group method d Old timber rules, since the modiiications due to local conditions are so manifold, requiring observation and judgment. Caution in not opening too much at a time and too quickly may avoid failure in securing good stands. In general, the first openings may contain from one-fourth to one-half an acre or more, and the gradual enlarging may progiess by clearing bands of a breadth not to exceed the height oi the surrounding timber. The time of the year when the cutting is to be done is naturally in winter, when the farmer has the most leisure, and when the wood seasons best after felling and is also most readily moved. Since it is expected that the seed fallen in the autumn will sprout in the spring, all wood should, of course, be removed from the seed ground. The fir
