174 JOURNAL OF THE ROYAL HORTICULTURAL SOCIETY, 
of cabbage, shown on page 46, are of course essential in " truck- 
farming/' which Mr. Corbett deals with chiefly. This department 
of olericulture (vegetable cultivation) should be clearly distinguished 
from market gardening, for it is described as an extensive rather 
more than intensive market gardening, because more or less remote 
and very large markets are catered for in preference to small local 
towns. Vegetables and fruit are grown upon a very large scale, as 
is shown by the extensive field in fig. 71, where celery is being trans- 
planted. Again, fig. 74, with its long lines of double-mouldboard 
type of celery bankers, will give an inspiriting impression to English 
people of the wealth that could be had from our own land or that of 
the Dominions if co-operative working colonies of growers were set 
to work under expert guidance. In speaking of those who grow for 
the trade, figures are mentioned which convey even to the uninitiated 
the gigantic size of these Garden Farms. One grower, we are told, 
uses 1 ton of seed on about 70 acres of land, and with this he is con- 
tinually raising young cabbage plants to send to other growers who 
again sell them. 
A large portion of the book should be read critically by the young 
student, because details of cultivation and of storage requirements 
which are no doubt applicable to the United States would not be 
useful in our climate. On the other hand, some of the pictures, which 
are so admirably clear, are instructive because they show with what 
care the vegetables are bunched and packed (note fig. 38, asparagus 
buncher, and Brussels sprouts, fig. 56), and the letterpress reminds 
us continually of the importance not only of cheap rates but of rapid 
transit facilities, combined with well-ventilated cars. Then, too, we 
are told how important it is to handle produce carefully, and that only 
perfect products yield good results when goods have, owing to climatic 
difficulties, to be pre-cooled before they start on their long journey in 
refrigerated cars. 
The information must all be sifted before it can be applied to 
English market gardening, but we certainly can learn much from the 
United States if we study alone their way of impressing knowledge 
upon the worker by means of clear illustrations. Our English books 
are often defective in having few and poor pictures.
