24 GARDENING FoR ALL. 
EXPLANATION. 
The accompanying plan is intended to show how the 
different kinds of crops may most advantageously follow each 
other in four successive years, so that the same find may not 
occupy the same ground two years in succession, and in 
order to economize manure and labour as well as to be 
most conducive in preventing various diseases and insect 
attacks to which the crops are liable. 
The numbers in the blank spaces in the diagrams for 
the second, third and fourth years, are intended to indicate 
that on those plots the crops should be planted or sown that 
are under the same number in the diagram for the first year. 
The rotation suggested may be altered and adapted to 
meet varied requirements in different gardens; a hard and 
fast rule not being desirable or absolutely necessary.
