EXAMINATION IN MENSUEATION AND SUEVEYING. 
Maximum Number op Marks, 100. Pass Number, 50. 
Thursday, April 16tJi, from 2 p.m. till 5 p.m. 
1. Find the area, iu acres, &c., of a border 40 ft. wide which goes 
all round a rectangular field 500 yards long and 330 yards wide. 
2. Calculate, in tons per acre, the weight of a quarter of an inch 
rainfall. (A cubic foot of water weighing 1000 oz.) 
3. State the rules for finding the volume and surface of a cylinder 
and cone. How would you deduce the volumes of the parts into 
which a cone is divided by a plane parallel to its base ? 
4. Eeckoning that a horse can draw a ton weight, in addition to 
that of the vehicle, how many horses should be set to draw 25 fir 
trunks, each 32 feet long and 18 inches in diameter at the base. 
(Specific gravity of fir wood being 0*64.) 
5. A rectangular heap of stones is formed on a base 20 feet long 
and 8 feet wide ; the slope on all sides is one vertical to one hori- 
zontal ; if it is made as high as possible what are its dimensions and 
volume ? 
6. There are four points A, B, C, D, marked on the ground, e.g., 
by flag staffs or by trees, and the area of the ground inclosed by 
A B C D is required ; it is found impracticable to measure the sides 
of the quadrilateral figiare ; accordingly the diagonal A C is measured, 
and it is required to mark on it the feet (M, N) of the perpendiculars 
drawn to it from B and D. How could this be done ? And if done, 
how would it help you to find the required area ? 
7. In the last example suppose that A C is 1200 yards, A N 500 
yards, N M 240 yards, and M C 460 yards, M B 520 yards, N D 380 
yards, draw the figure A B C D to scale, note the lengths of the sides, 
and determine its area. Supposing that the determination of the 
positions of M and N are liable to small errors (say of a few feet), 
why should this cause more of error in the plotted lengths of the 
sides, than in the calculated area ? 
8. The angles of a triangle are measured ^and are found to be 
81° 50', 28'' 40', and 69^ 30', and the shortest side is 520 feet; draw 
the triangle to scale and calculate the length of the longest side. 
9. Describe briefly the method of determining tlie levels of points 
along a given line, as along a road. What is a contour line '?
