fenced, but the less diversity of bearing the better. When road-lines sever sections the areas of the severed portions, and also the total net areas of the sections, are to be shown on the map.

Form and scheme of sections.

32. Sections are to have as nearly as practicable a depth of not less than twice the width or frontage to a road, stream, lake, or coast; but where the land is open for selection before survey the sections must have a depth of not less than 40 chains, and must conform to a general scheme, with frontages, depth, &c., as may be approved by the Chief Surveyor and the Land Board.

Boundaries, how marked.

33. All boundaries of blocks and sections are to be pegged at every angle. In open country, straight boundary-lines under a mile in length must be cleared where necessary, and distinctly marked by pegs and lockspits at intervals not exceeding 20 chains, or 30 chains on lines that exceed one mile in length, which, however, at the discretion of the Chief Surveyor, may be varied to suit the conformation of the country. Advantage should be taken of the most prominent and favourable positions on the line for the pegging, so that the direction may be seen from peg to peg.

34. In forest country the boundary-lines must be cut, ranged, and pegged in the same manner, and at similar intervals, advantage being taken in rough country of ridge-crossings for the pegging, in which case, where measurements are not required, subject to the approval of the Chief Surveyor, only such cutting of the line will be required as will insure adjacent pegs being visible from each other, but it must be sufficient to enable the distances of such pegs along the line to be arrived at approximately for showing on the map. Under any circumstances the lines must be cut from the frontage from 3 to 5 chains and pegged, but should the peg come in an impracticable or unsuitable position for extending the line, then the cutting must be continued until the peg can be placed in a position that will enable this to be done, and in either case its distance from the front peg must be noted in field-book and on maps.

Pegging at intersections.

35. The points of intersection of all section-lines with traverse-lines are to be pegged, measured to, and noted on the map, and should the section-pegs be off the traverse-lines, the distances of the section-pegs from such points should also be given. The measured or calculated distances from the section-pegs to the adjacent road-angle pegs on same side should be given, and the boundary of a section intersecting a road must in all cases be pegged on the traverse-line as well as on both sides of the road.

Line-cutting.

36. Lines in bush must be cut and cleared four feet wide, the scrub cut close to the ground, and overhead seven feet from the ground. All trees three feet through and under to be cut down, and the height of the stump should not exceed its diameter. In open country, with scrub, the lines must be cut and cleared at least two feet wide.

Traverses and trig. connection.

37. In traversing, the surveyor is to proceed to the nearest trig. station and base his work on the circuit meridian, clearly denoting on the plan the line and the bearing so used, and the coordinate value in terms of the initial of the circuit. Connections should be made with trig. stations or other established points when opportunity offers to test the accuracy of the work. Surveyors are to report as to trig. stations requiring repair.

All traverse stations should be pegged before being measured or observed to, and the surveyor when at a trig. station should take readings to traverse or subsidiary stations in view. All check bearings should be repeated and thrown forward, so as to limit the accumulation of instrumental errors, and checks and closures must be noted in the field-book. Vertical angles are to be observed by theodolite to reduce all inclined measurements to their horizontal values,
