purpose. At present the seed is imported annually, chiefly from Ma- 
deira. Cultivation of the plant on a large scale only dates from about 
1245. Seeds of all the best varieties cultivated in Europe were sent 
from the Royal Gardens, Kew, in 1873, and widely distributed ; 16 sorts 
were tried at Mount Langton. The writer could never ascertain that 
any of them commended themselves to the growers as superior to the 
sorts they were accustomed to sow. 
Onions in Bermuda are sown in October and November, set out in 
November or December, and pulled for market in April and May. The 
export reached the large quantity (for the area of the islands) of 4,180 
tons in 1875, which has not since been exceeded.
