Agricultural Education : 
A body moves from rest ; its velocity undergoes a uniform accelera- 
tion of 32 in feet and seconds ; find the distance it describes in the 
seventh second of its motion. 
7. Two weights of 130 lbs. and 110 lbs. are connected by a fine 
thread, which passes over a small pulley turning on a very smooth 
axle ; the heavier weight is allowed to descend, drawing up the 
lighter weight ; at what rate per second are they moving at the end 
of the third second of the motion ? What is the magnitude of the 
tension of the thread ? 
8. State the law of the transmission of pressure through water ; 
explain the construction of the hydraulic press sufficiently to exemplify 
this law. 
Describe the leather collar by means of which the press is enabled 
to work water-tight. 
9. What is the dew-point ? 
By what simple experiment could you show that on a fine summer 
day the air contains moisture ? 
Speaking generally, does the air contain more moisture in summer 
than in winter ? Give briefly a reason for your answer. 
EXAMINATION IN MENSURATION AND 
SURVEYING. 
Maximum Number of Marks, 100. Pass Number, 50. 
Thursday, April 19th, from 2 p.m. till 5 p.m. 
1. State .the rules for finding (a) the area of a quadrilateral figure 
with two sides parallel ; (b) the area of a circle ; (c) the area of the 
surface of a cylinder ; (d) the volume of a pyramid or cone. 
2. A B C D is a quadrilateral figure ; the side A B is parallel to 
and shorter than the side C D : show how to draw through A a line 
dividing the area into two equal parts. 
3. A circular pipe 4 inches in diameter is found to deliver 200 
gallons of water a minute ; at what rate (in miles per hour) does the 
water move through the pipe? (A gallon contains 277,274 cubic 
inches.) 
4. A square field of 40 acres has a border 30 feet wide trenched 
round it ; what is the area of the border in square feet, (a) if it be 
inside the field, (6) if it be outside the field ? 
5. A large area is to be planted with trees in rows, so that from 
tree to tree may be 20 feet ; what distance is there between any two 
consecutive rows, and how many square feet are allowed for each 
tree?
