It is repeated here, with an increased convic- tion of its truth, that rain water and irrigation are the best and only necessary forms of applying liquid manure to the land. The nitrogenous phosphate manure mentioned at page 20, is cheap in its manu- facture, and an efficient mode of employing urine in a convenient manner.
