11. Officers of the division generally will be assisted by the D.A.Q.M.G.s as far as practicable, in pursuing their studies in other branches.
12. A diary will be kept showing the names of all officers attending, the hours of attendance, the work done, etc.; this diary is to be submitted for the inspection of the Lieutenant-General commanding, and from it a monthly report will be prepared for the information of the Field Marshal.
13. Officers will be allowed the use of surveying instruments but will have to provide their own drawing and other materials. They will, however, be permitted to retain all sketches, plans, and reports thus made on their own materials, after they have been returned from the Council.
The course actually carried out in 1868-69 was as follows:
Explanation, use, and construction of scales—several examples worked and a plate of scales drawn—mode of using the usual drawing instruments, protractors, and Marquois’ scales.
Use of the prismatic compass—a road is traversed with the compass—bearings and measurements entered in a field-book, and the result plotted indoors on a large scale.
A plate of the conventional signs used by the topographical department, and a set of the seven examples of shading ground (by the late Major Petley), according to the latest scale of shade, are given to each officer to copy.
The general principles of plan drawing, and the mode of conducting a survey by means of measuring a base, and by a triangulation, are explained, and a flat piece of ground is sketched with the compass, and plotted in the field.
The method of representing ground by contours only is now explained and illustrated by models, drawings, etc., and it is shown how from a contoured plan sections and elevations of ground are made, also how by adding shade to the contoured plan, a certain pictorial effect is produced, etc.
Abney’s pocket level and clinometer is explained, and various modes of rough levelling illustrated.
