it necessary to mow five times during the season ; he has found 

 by actual measurement, that his rye grass sometimes grows two 

 inches in twenty-four hours. Mr. K. dilutes his liquid manure 

 with four parts of pure water, and lays it on the land six times 

 each year. The fertility of the soil increases rapidly, notwith- 

 standing the frequent cropping ; before the liquid manure was 

 applied, it would not keep five sheep to the acre, now it will feed 

 twenty. 



Mr. Cuthbert W. Johnson, in his Cottage Gardener, vol. 5, page 

 39, reports that he laid down a plot of grass in his garden, six- 

 teen yards long and thirteen yards wide, containing two hundred 

 and eight square yards, and that he applied to it in a liquid form, 

 the sewerage of liis house several times between March and Octo- 

 ber, during which period he cut the grass twenty-five times, and 

 secured 1,295 pounds, which is at the rate of thirteen and a quar- 

 ter tons per acre. 



Mr. Robert Neilson, merchant of Liverpool, leases a farm of 

 three hundred and fifty acres belonging to the Earl of Derby, 

 eight miles from that city, one hundred and twenty acres of which 

 he fertilizes with liquid manure, applied by a steam engine, iron 

 pipes, &c. In his report to the agricultural society, he declares 

 that by repeated applications of liquid manure, he accomplished 

 the feat of raising, on a well drained favorable plot of ground, 

 previously in excellent condition and very fertile, one hundred 

 tons of green crop, consisting of Italian rye grass and clover 

 from an acre of land, within a year. 



I think earthen pipes may be substituted for iron, successfully; 

 they are incorrosive, and iwo thirds cheaper ; some that I have, 

 which were imported, will not yield to any head of water, less 

 than eight hundred and fifty feet, and three hundred feet is the 

 proof pressure applied to iron pipes. 



If pure water is used as a fertilizer, it should be applied accord- 

 ing : 



1. To the object of the culture : when for leaves more water 

 should be given than when for flowers; less water should be given 

 when for fruits or grains.
