Only gradually was the character of these plans brought into practical form, and their execution, in spirit at least, enforced, the Conservators having the right to deviate from the plans. A map, prepared by the survey branch naturally forms the basis of the plan. The form of the plan is prescribed by the provincial regulations, and the preparation is also carried on by the provincial service under advice and supervision of the imperial department. The “strip valuation survey,” which Brandis introduced, covering sometimes as much as 30 per cent. of the area, is employed in determining number of trees and sizes, growing stock and cut, modeled after the European practice, except that little, perhaps too little, money is spent on their elaboration, especially on determining the proper amount of cut. That the cut is controlled at all is the most important result. 6. _Education and Literature._ In 1866, Sir Dietrich Brandis selected as assistants two young men who had been trained in the forest schools of Germany--in turn his successors--and at the same time arrangements were made for the training of young Englishmen in the Forest schools of France and Germany. At the end of 1875 the professional education was entirely transferred to Nancy. The present force of Conservators is composed largely of these men. For some reason, the training of men in Germany and France became unpopular, and this objection finally led, in 1884, to the establishment of a chair of forestry at Cooper’s Hill College for Engineering in England. At first, the course of study extended over 26 months, during 22 of which the candidates prosecuted their studies at the college; the remaining four months being spent under suitable supervision in selected British and Continental forests. In 1905, this department was transferred to Oxford University and the course extended to three years, one year to be spent in continental forests. At present this time may, however, be reduced to two years and the vacations in continental forests. This is a government affair, and probationers receive stipends from the government.
