Sc?iior Examination Papers, 1877. 
12 r Your home-bread fattening sheep, at say ono year old, may 
average 10t stone each, live-weight ; at how much would you estimate 
the carcass-weight, and what would they realise per head at Gs. lQd. 
per Smithfield stone? 
13. Mention the several classes of improvements recognised by tbe 
" Agricultural Holdings (England) Act, 1875." 
14. You wish, as much for shelter as for ornament, to fence off and 
plant, in a 100-acre pasture, four clumps of trees, each to contain f of 
an imperial acre. Of what shape would you construct them in order 
to take least fencing, and what would it cost you to rail off the whole 
four at 8s. per rood of 7 yards. 
15. Define the term " manure." 
16. On what soils and in what situations is steam cidtivation most 
to be recommended ? and what are its main advantages as compared 
with team-work? 
17. At 8d. per head per week, eaten on the ground by sheep, what

common turnips respectively ? 
18. What soils do you reckon most suitable for the growth, respec- 
tively, of swedes, white turnips, and man gold- wurzel ? and what weight 
per acre is considered a good crop ? 
EXAMINATION IN CHEMISTEY. 
Maximum Number of Marks, 200. Pass Number, 100. 
I. General Chemistry. 
Wednesday, April 18th, from 10 a.m. till 1 p.m. 
1. What compounds does carbon form with oxygen, and under 
what circumstances are they severally formed ? Describe the chief 
characters of each of these compounds, and explain how its composi- 
tion has been determined. 
2. Describe the preparation and chief properties of chlorine. Ex- 
plain its action on (1) potash, (2) ferrous sulphate, (3) alcohol. 
3. Define equivalent weights, also neutral salts; and illustrate 
your definitions by examples. Find how much lead nitrate will 
exactly decompose 100 grs. of common sodium phosphate. 
(N : P : Na : Pb = 14 : 31 : 23 : 207.) 
4. Point out the several sources whence nitrates in spring-water 
are derived, explaining how they are produced in each case. In what 
cases is spring-water most liable to be contaminated by passing 
through leaden pipes, and why ?
