JERUSALEM ARTICHOKE.— (Helianthus tuberosus). 
This species of sunflower, which produces the so-called 
‘“‘ Jerusalem Artichoke,” was originally introduced from the 
Northern United States. It has been cultivated in England 
as an article of food since early in the seventeenth century. 
The tuber does not contain starch, hence it is not floury 
when boiled. 
Being a most wholesome and easily grown vegetable, it 
should be grown in every garden. It will flourish in almost 
any soil, and does not require much manure. It is also most 
accommodating as to aspect and sunshine, and will thrive in 
positions where many vegetables would fail. 
Growing six to ten feet high, and being covered with 
large, bold, and artistic-looking foliage, it forms an admirable 
screen during summer and autumn for unsightly objects and 
corners in a garden. 
Its stalks and foliage form also an excellent forage for 
cattle and rabbits, and might be more utilised for these 
purposes in rural and woodland districts. 
Plant on deeply dug soil, in rows thirty inches apart and 
fifteen inches apart in the rows, and six inches deep. Plant- 
ing may be done any time from the end of November to the 
end of March. 
ONIONS.— (Allium cepa). 
The onion is unquestionably entitled to rank amongst the 
oldest of cultivated vegetables. It has a wide geographical 
distribution, but it is supposed to have originated in 
Turkestan. But of cultivated forms of the Allium, the onion 
does not stand alone. In addition we have the Welsh Onion 
(A. fistulosum), Leek (A. porrum), Potato Onion (A. 
aggregatum), Shallot (A. ascalonicum), Garlic (A. sativum), 
Chives (A. Schcenoprasum), and Tree Onion (A. proliferum). 
A good crop of onions is one of the most profitable of 
vegetable crops, and is worth from £40 to £60 per acre; an 
exceptionally fine crop in a bad season being worth much 
more. A good average crop would be about ten tons to the 
acre, these, at £4 per ton, would be worth £40. But crops 
at the rate of fifteen, eighteen, and twenty-two tons per acre 
have been produced; these are exceptional crops.
