Uniformity of lines to be preserved in laying out sections. 58. The preliminary traverses having been executed, the next process is to subdivide the block into small sections. As it is the custom to sell land in this Province prior to survey the selections usually vary greatly in size and shapes, and consequently it requires some discrimination on the part of the Surveyor to scheme these purchases into sections complying with the terms of the application, and at the same time to preserve uniformity of lines. The following are the chief points to which attention is directed : — The sections should be generally in rectangular figures, and if possible, lying in the direction of the Meridian and Perpendicular. As the frontages upon road lines, rivers, streams, &c, vary in proportion to the number of acres applied for, these measures are to be calculated upon the back line, which is invariably to be placed at an average distance of forty two chains from the frontages in cases where the percentage for road allowance is included, or of forty chains when this allowance is withheld. When a number of applications lie together, no unpurchased land should be permitted to remain intervening excepting in such quantities as to form other sections. Allowance for Roads. 59. The allowance for roads is to be made as follows :— On purchases under 500 acres an allowance of 5 per cent. On purchases above 500 acres and under 1000 acres 4 per cent. On purchases above 1000 acres 3 per cent. For example, an application for 400 acres will require that 420 acres be laid off on the ground, and the total average is written thus on the map : 400 + 20 ; and similarly that for 900 acres should be marked out equal to 900 + 30 acres. Method of laying out 5s. Land. 60. The regulations affecting 5s. land demand that the sections should range from 80 + 4 acres to 320 + 16 acres. In large applications as great a number as possible of these section lines are so schemed as to intersect at or pass through the Trigonometrical stations, and their dimensions are based accordingly upon these points. Former surveys to be verified. 61. In cases where sections have been previously laid out the pegs should be sought for, verified, and connected with some point in the new survey. When the pegs of former survey cannot be found, and the owners on application refuse or are unable to point them out, then they should be replaced in accordance with information supplied from office maps and Crown Grants. Relation between section and survey line's. 62. If the section lines are based upon Trigonometrical stations a bearing and distance deduced by computation should be recorded from every Trigonometrical station to the nearest intersecting lines, but when they are based upon traverses or conjunctly upon Trigonometrical and traverse stations the points of impingement of the section lines upon the traversed lines should also be calculated and recorded from the nearest traverse station. Method to be pursued for fixing sectional corners. 63. In open country it will generally be found that the corners of sections can be conveniently and very accurately determined by running lines, either on the bearings of the section lines or on those as computed from the Trigonometrical or other well fixed points in the survey, until they intersect each other at the point desired. (See paragraph 53.) It is recommended in the latter case that the points of intersection should be determined by at least three such bearings, as their near coincidence will be an indication of the accuracy of the work. It is very necessary that proper precautions are taken to preserve the true direction of these lines by referring as opportunities offer to points which will furnish check bearings. In bush or partly bushed country a system combined of chained and of intersecting lines should be adopted. Manner of marking Section Corners. 64. The corners of sections are to be marked with a block of totara 6 inches square and 2 feet in length, leaving only 4 inches above the surface of the ground, also with the usual Government iron peg and with lockspits dug three feet long and one foot in width and depth in the exact direction of the section lines, and further to indicate the true direction of these lines for fencing and other purposes pegs are to be driven at any convenient distance from the corner peg. Too much care cannot be bestowed to ensure the durability of these marks. The angular points only of the boundaries of land comprised in one Crown Grant to be marked on the ground. 65. When a number of sections are comprised in one Crown Grant, only as many of the corners as are also the angular points of the external boundaries of the Crown Grant are required to be marked on the ground, and it is not necessary to cut or to indicate throughout the direction of the lines between any two such corners provided the pegs can be determined by other more direct means. Bearings should be given from the corner peg or from some point near to two or more survey marks in view. Scale for Maps. 66. The scales to be adopted for Maps unless special directions to the contrary should be given are : For Townships — 1 Chain to an inch for small portions. 2 Chains to an inch for general plans, containing ¼ acre allotments. 3 and 4 Chains to an inch for general plans, containing 1 acre allotments. For Suburban and Rural Sections — 4 and 5 Chains to an inch for blocks under 500 acres 6 and 8 Chains to an inch for blocks from 500 to 1000 acres
