History, Use, Propagation, Culture, 
not find their way into the plantation. Near Rickmansworth, in Hertfordshire, there is a fine stream of 
water on a chalky bottom, in which one cultivator grows five acres, and sends a supply to London every 
day in the year, Sundays excepted. There are also large plantations at Uxbridge, Gravesend, and other 
places. 
Some market-gardeners, who can command a small stream of water, grow the water-cress in beds sunk 
about a foot in a retentive soil, with a very gentle slope from one end to the other. Along the bottom of this 
bed, which may be of any convenient length and breadth, chalk or gravel is deposited, and the plants are 
inserted about six inches distance every way. Then, according to the slope and length of the bed, dams are 
made six inches high across it, at intervals ; so that when these dams are full, the water may rise not less 
than three mches on all the plants included in each. The water, being turned on, will circulate from dam to 
dam ; and the plants, if not allowed to run to flower, will afford abundance of young tops in all but the winter 
months. A stream of water no larger than what will fill a pipe of an inch bore, will, if not absorbed by the 
soil, suffice to irrigate in this way an eighth of an acre. As some of the plants are apt to rot off in winter, 
the plantation should be laid dry two or three times a year, and all weeds and decayed parts removed, and 
vacancies filled up. Cress grown in this way, however, is far inferior to that grown in a living stream flowing 
over gravel or chalk. 
The water-cress has lately been cultivated in the neighbourhood of Paris, and also near Edinburgh. 
1384, Lepiocarpcea. From Xizro;, slender, and xa.^'xov, fruit. A genus distinguished from Sisymbrium by 
its accumbent cotyledons.
