To carry out this rotation, the farm is divided into four fields, and I cannot 
do better than give you a table prepared by Professor R. Hedger Wallace, who 
used to lecture on agriculture in Victoria :— 
Four-couRSE OR Norrotk RorTatION.

First Year } Turnips, and 
Swedes 
Second Year : Barley Clover Wheat Fallow 
Third Year Ags Clover Wheat Fallow Barley 
Fourth Year Wheat Fallow Barley Clover 
The first thing you must notice about this rotation is that half the farm is 
producing wheat and barley for market ; and half, fodder for sheep. Also, that 
the fodder crops are grown alternately with the corn crops, and that the first 
fodder and corn crops are surface feeders, and the second subsoil feeders. 
Further, that the land undergoes a thorough tillage and cleaning every fourth 
ear. By the frequent growth of fodder crops and thorough tillage, the 
ertility of the land is kept up. 
In a future lesson I will more fully explain the important matter of 
rotation of crops. 
Questions on Lesson 6.

SECOND STAGE. 
Before we begin this lesson I want to impress upon you that this and all 
‘the foregoing lessons are only easy steps to a higher and more scientific study 
of the profession of agriculture. Do not imagine that you know all about the 
soil and manures, and about renovating worn-out soils from what you have 
read. You have merely been climbing the lower rungs of the ladder, and it is 
a very long way to the top; but with patience, diligence, and a determination 
to succeed you will get there all right. There was a funny man who once said 
to a person who thought himself very wise: “The man who does not know 
anything and pors nor KNow that he does not know anything is a hopeless 
case; but the man who does not know anything and Knows that he does not 
know anything is pretty sure to go ahead.” So just bear in mind that there 
are many things you do not know, and never be ashamed to confess that you 
do not know. Ask questions—sensible ones, of course. Get to know the 
reason for every agricultural operation you see being done. Do not rest content 
with learning out of a book. Books are all very well; but they are only meant 
as helps to the understanding. Use your eyes, your intelligence, and your 
hands. No profession can be learnt without practice. What sort of a sailor 
do you think a man would make who had learned by heart’ every part of a
