" Not so big that It need frighten the ardent amateur, nor so much of a primer that it 

 may be disdained by the fairly accomplished gardener, it has a good scheme. The first 

 part, consisting of eight chapters of general principles, in simple, non-technical language. 

 is a model of useful information in a small space ; the second part deals with departments 

 of gardening ; the third, with types of flowers, and the fourth is a calendar to work by."
