wish to proceed to microscopical work. The materials used in the lessons are 
easily obtainable by the student and are so chosen that each point to be demon- 
strated can be seen with the naked eye. 
The first chapter contains valuable sug- 
gestions on the keeping of notes and the 
labelling of drawings. Subsequent chapters 
deal with Seeds and .Seedlings, Conditions of 
Germination, the Food of Plants and how it 
is obtained. Stems, Roots, Leaves and their 
Modifications, Flowering and Non-flowering 
Plants, Green and Non-Green Plants, the 
! Structure of Flowers, and so on. Some 
I chapters are also devoted to Vegetative Ke- 
1 production. Fertilisation, Hybridisation and 
i Selection, and to Parasitic Fungi. There is 
I also advice on the treatment of injurious in- 
I sects, and information about those which may 
be considered to be the horticulturist’s friends.

The fungoid diseases of plants are tabulated, as indeed are the insect pests 
(see Figure 25). An appendix contains a list of the various families of Flowering 
Plants and Ferns, and the chief plants in cultivation, while the chapter dealing 
with methods of answering questions on paper should prove a very valuable aid 
to students who sit for the Royal Horticultural or other Societies’ examinations. 
Special mention must be made of the excellent annotated diagrams (see 
Figure 23), which form one of the principal features of the book, and which 
should greatly help to make the work clear and intelligible to those who are 
unable to attend courses of horticultural lectures. Masters in primary schools 
where gardening is taught will find much that is of value to them in the manage- 
ment of a school garden.
