unit of area. Next and almost equal to the Potato comes the Beet; 
well below these is the Jerusalem Artichoke ; and below the Artichoke 
the Parsnip and autumn Cabbage. Among the lowest are garden 
Peas. So that, when intensive cultivators are urged to grow Peas, 
they are being told to grow what, in fact, is a luxury crop. It is true 
that it contains per pound of dry weight far more protein than is con- 
tained in an equal weight of Potatoes, but when the relatively low 
yield of Peas is taken into consideration, the far greater value of the 
Potato becomes apparent. 
Whether Haricot Beans would be a profitable crop from this point 
of view we have not the data to determine. It is probable that it 
would; but in the meantime it is evident that the Potato should occupy 
in these times a large space in any scheme of cropping, and that gar- 
den Peas and Brussels Sprouts, which give a low yield per acre, should 
be grown only on a restricted scale. 
There are, of course, other factors to be taken into consideration 
in estimating the food values of vegetables. One of these is the rich- 
ness of vegetables in what are known as accessory food bodies — bodies 
the special function of which is to stimulate and regulate growth. 
The relative -values of different vegetables from this point of 
view have not been determined, but it is probable that the instinct 
which leads men to eat vegetables so relatively low in the scale of 
food values as Onions, Carrots, and Tomatoes indicates that these 
vegetables are rich in the essential accessory food substances. 
Much more might be done to economize in land by under-cropping 
in orchards with vegetables. It is better for the trees than luxuriant 
grass, and the cultivation and manuring of the vegetable crops tends 
to produce freedom of growth in the fruit trees. 
A part of the Royal Park at Richmond has been given over to the 
culture of cereals and forrage crops. The work is being done with 
automobile plows of which the greater part have been given by pri- 
vate individuals. In many parts of England these plows, equipped 
with acetylene lamps, are being used by night as well as by day. 
Experts have decided that most of the parks of London will not 
lend themselves to agriculture, but portions of Hyde Park and Regent's 
Park will be divided and used for allotment gardens. 
In all parts of England gardens are being cropped with the great- 
est care and economy and all unused lands are being divided into 
allotments. The time has come when the food supply means victory 
or defeat and a country that has always loved growing things knows 
how to marshal its experience, its knowledge and its resources to a 
glorious end.
