"The next year the weather was wet, grain soft and not in very good order, but the following was the amount of produce:—
Wheat grown with Uncovered Manure.

| Produce in grain. | bushel. | Produce in straw. | ||||
| Acre. | bushels. | lb. | lb. | stones. | lb. | |
| First | 41 | 19 | 61-1/2 | 152 | of | 22 |

Wheat grown with Covered Manure.

Drainings of Manure-heaps.
The importance of not separating the liquid portion from the solid portion has already been pointed out in dealing with the composition of the solid excreta and the urine. These two constituents of the manure are complementary to one another, and the value of farmyard manure as a general manure is very much impaired if the liquid portion is not applied along with the solid. In one important respect do the drainings of manure-heaps differ from urine—that is, in the percentage of phosphates they contain, the latter being practically devoid of phosphoric acid.
The following is an analysis of drainings from a manure-heap (Wolff):—
| Dry substance | 18.0 |
| Ash | 10.7 |
| Nitrogen | 1.5 |
| Potash | 4.9 |
| Lime | 0.3 |
| Magnesia | 0.4 |
| Phosphoric acid | 0.1 |
| Sulphuric acid | 0.7 |
| Silica | 0.2 |
