and a side of tlie ground plan is 20 feet externally ; it is built 2 
bricks thick ; bow many rods of brickwork does it contain '? 
3. Wbat is prismoid ? and wbat the rule for finding its volume ? 
A tank lias a uniform dcptb of 10 feet, the top is a rectangle 50 feet 
by 20 feet ; the bottom is also a rectangle with corresponding dimen- 
sions 40 feet and 10 feet; the remaining sides are trapezoids; how 
many cubic feet of water can it contain '? 
4. Two sides of a plane triangle are respectively 573 and 311 
chains, and the angle included between the sides is 21° 18' 30" ; find 
its area in acres. 
5. Given a wholly inaccessible point (say on the other side of a 
stream) and a line (on this side of the stream) marked out by two 
pickets ; how would you find the foot of the perpendicular let fall 
from the point on the line, if you had nothing but a measuring tape 
and pickets? 
6. Plot the following notes, and 
determine the area of the field (use 
as large a scale as your paper will 
admit). 
7. Plot the following notes, and 
determine the difierence of the levels 
of the extreme stations (use as large a 
scale as your paper will admit).

8. If AB is a line 370 feet long, and if P is a distant point, given 
that the angle PAB is 71° 43' 20" and the angle PBA is 95° 12' 40", 
find the distance of P from A. 
9. A, B, C, are three consecutive milestones in a straight line from 
a point P, the angle APB is 30" and BPC is 45° -.—first, lay down the 
position of P by construction ; secondly, calculate the distance AP.
