"There are four chapters for the study of agriculture, of the highest practical importance," resumed Scrofa, "namely:"
1° What are the physical characteristics of the land to be cultivated, including the constitution of the soil;
2° What labour and equipment are necessary for such cultivation;
3° What system of farming is to be practised;
4° What are the season? at which the several farming operations are to be carried out.
Each of these four chapters may be divided in at least two subdivisions:
The first into (a) a study of the soil, and (b) a survey of the buildings and stabling.
The second into an enquiry as to (c), the men who will carry on the farming operations, and (d) the implements they will require.
The third into (e) the kind of work to be planned, and (f) where that work is to be done.
The fourth into what relates (g) to the annual revolution of the sun, and (h) the monthly revolution of the moon.
