Curve 10 chains rd from 0 chains to 5 chains and from 25 chains to 30 chains. 99 20 chains rd from 60 chains to 70 chains and from 90 chains to

100 chains.

Maximum velocity 5′ per sec.

Drainage area 1,000 square miles, undulating and densely timbered.

2. At the Melbourne University (Latitude 37° 48′ South and Longitude 9 hours 39 minutes 50 seconds East) on 12th October, 1895, the altitude of the sun's lower limb was observed with the sextant and artificial horizon, when a watch

set approximately to standard time indicated 4 p.m. The observed double altitude is 58° 8′ 40′′, and the correction for index error of the sextant + 2′ 40′′. Determine the error of the watch on standard time.

(Honour candidates will compute the local sidereal time of the observation.)

Data extracted from Greenwich Nautical Almanac, 1895 :—

ADVANCED SURVEYING.

SECOND PAPER.

The Board of Examiners.

1. Describe the methods adopted for determining the positions of soundings, and show what precautions are necessary to obtain a good fix.

2. What is the hydraulic grade line of a pipe track, and how do variations in the sizes of the pipes affect it?

The water level in a reservoir is RL 100-00, . and a pipe 12 inches in diameter leaves it at RL 80-00, discharging at a point three miles distant at RL 40-00, the pipe being below the hydraulic grade line throughout. What is the discharge in gallons per minute?

3. A railway survey is to be effected between two points separated by a high range of mountains. How would you proceed to do it, and what points would demand the most attention ?

4. How would you compute the storage capacity necessary in a reservoir for water supply of a town having a population of 50,000? Illustrate your answer with an example.

5. What are the points to be attended to in selecting a harbour of refuge?

DRAWING AND QUANTITY SURVEYING.

The Board of Examiners.

1. Plot the surface and formation levels given below to a suitable scale, fill in the depths of cuttings and heights of banks, and compute the quantities of earthwork in cutting and embankment, the formation width being 20 feet and side slopes 1 to 1 in cutting and 1 to 1 in bank.

2. Prepare a list giving quantities and sizes of timber you would require to make the table at which you are working.

MECHANICAL DRAWING AND DESCRIPTIVE GEOMETRY.

The Board of Examiners.

1. Describe fully the following projections used in mapping :

(a) The simple conical projection.

(b) Mercator's projection.

2. Draw an ellipse whose major diameter is 6 inches and minor diameter 4 inches.

3. Draw a cycloid, the diameter of the generating circle being 3 inches.

4. Draw a circle 2 inches diameter surrounded by eight equal circles, each of which touch the main circle and the adjoining ones on either side.

APPLIED MECHANICS.

FIRST PAPER.

Professor Kernot.

FOR PASS AND HONOUR CANDIDATES.

1. Write an essay upon wind pressure, appliances for measuring the same, and its effect upon engineering and architectural structures.
