164 EPPING FOREST within these Manors thinning on a greatly reduced scale now meets the case. In concluding this part of my subject, let me urge that every one who aspires to be a forester should exercise his imagination. He works for posterity. It is essential for his success that he should, with full knowledge of natural processes, have ever present in his mind the probable results of his operations, not only in this generation, but fifty or a hundred years hence. Drainage.—In this case I am inclined to give Punch's advice to those about to marry. In the Forest, covered drains are sooner or later choked by roots, and open water-courses are quickly trodden in by cattle. No doubt to a certain extent it is necessary to lay dry those tracks which are much frequented; but I think that labour em- ployed in draining swampy hollows is worse than wasted, because, in their natural state, they have a distinct flora, and insect life, of their own. Above all, I deprecate any attempt being made to straighten and formalise the beautiful natural water-courses at the bottom of the hollows. In some cases a perfectly straight-cut ditch has been substituted many years ago for the old water- courses, and the latter may be still traced as a shallow winding hollow. I strongly advocate restoring the stream to its old bed, by excavating it and filling up the straight cut. After a few years the old natural conditions and appearance are restored. This has been done with great success in part of the course of the Ching below Connaught Water, and I hope the process will be carried further. The Use of Carts.—Great mischief has been done in the past by the use of carts for the purpose of removing gravel and wood thinnings. When a ride has once been cut to pieces in this way, it is years before it recovers, the surface being so ploughed about, that it holds water like a sponge, and only recovers its solidity after a long period. For nearly twenty years I have strongly advocated the plan, which is almost universal on
