A separate branch of the forest service carried on the work of surveying and mapping the forest area instead of the regular Survey of India, with the result of cheapening the cost. Some 74,000 square miles had been mapped on the scale of 4 inch to the mile, the standard, some smaller areas on smaller scale, at the rate of $25 per square mile. In 1908, however, this work was handed over to the Survey. _Silviculture._ Silvicultural practices are naturally but little developed. Protection against fire, grazing, overcutting has been the first requisite. The unregulated selection system with a diameter limit, which Brandis introduced, still prevails mostly, although beginnings of a compartment and group system in converting miscarried selection forest of Deodar, Pine and Sal have been made, or rather of an improved selection method, which seeks to secure reproduction in groups. Clearcutting with seed trees held over is practised in the coniferous mountain forest. Coppice and coppice with standards (reserves of sprouts) is a natural condition over large areas, especially with Teak and Sal. Even improvement cuttings or sowing on barren hillsides with remarkable success, are not absent. The attempts at securing reproduction, especially in the truly tropic forests have often miscarried, inferior species filling the openings. Girdling of inferior species to favor the better classes has hardly had the desired result. In the deciduous forest, the same difficulty of undesirable aftergrowth is experienced, deteriorating the composition, except in the case of the gregarious Sal tree (_Shorea robusta_), the treatment of which for reproduction has, after many failures, been well established. Other gregarious species also can be satisfactorily reproduced. The culled and burned-over forests, of which, there are many, are re-habilitated in a manner by merely removing the old overmature and defective timber, with comparative success. In some parts, the large gregarious bamboos are a serious obstacle to reproduction. Here, the only chance for reproduction exists when they flower and die. Killing the bamboos by cutting the annual shoots proved a failure, but burning over the whole area and sowing seems to be followed by success.
