2. A B C D is a four-sided figure ; A B is 1,270 ft. long, and the 
following angles are measured, viz., D A B = 123°, C A B = 31° 30', 
DBA=43° 20', CBA=135°; draw the figure to a scale of 
500 ft. to an inch, and note the length of the side C D, and of the 
diagonal A C. 
3. A brick measures 8| X 4|- X 2J in. ; if bricks could be 
stacked quite close and without mortar, how many would there be 
in a rod of brickwork (i.e. 30^ sq. yds., a brick and a half thick) ? 
4. A rectangle has two edges horizontal, and its plane inclined 
at an angle of 25° to the horizon — like the cover of a book lying 
on a table and kept partly open ; the horizontal edges are 50 ft. 
long, the others are 30 ft. long ; find, by construction, the inclina- 
tion of a diagonal to the horizontal plane. 
5. Draw a line 4 in. long, and divide it accurately into 15 equal 
parts. 
6. A B is a side of an ornamental piece of water ; at A, where 
the stream enters, there is a waterfall of 4 ft. ; at B, where the 
stream goes out, there is a fall of 5 ft. ; at a point C, a little above 
A, there is a sluice by which the stream can be sent along a semi- 
circular watercourse to D, a point just below B ; from C to D in a 
sti-aight line is 800 yards ; what is the fall (in inches per hundred 
feet) of the stream when it is being carried along the semicircular 
watercourse 1 Show, in a sketch drawn to scale, the point of the 
watercourse which is on the same level as the piece of water.
