1. The silicate of potass was manufactured at a glass-house, by fusing equal parts of pearl-ash and sand. The product was a transparent glass, slightly deliquescent in the air; it was ground to powder under edge-stones.

2. The manures termed superphosphate of lime and phosphate of potass, were made by acting upon bone-ash by means of sulphuric acid, and in the case of the potass salt neutralizing the compound thus obtained, by means of pearl-ash. For the superphosphate of lime, the proportions were, 5 parts bone-ash, 3 parts water, and 3 parts sulphuric acid of sp. gr. 1.84; and for the phosphate of potass, 4 parts bone ash, water as needed, 3 parts sulphuric acid of sp. gr. 1.84; and an equivalent amount of pearl-ash. The mixtures, of course, lost weight considerably by the evolution of water and carbonic acid.

3. The medicinal carbonate of ammonia; it was dissolved in water and top-dressed.

4. Plot 5, was 2 lands wide (in after years, respectively, 5a and 5b); 5¹ consisting of 2 alternate one-fourth lengths across both lands, and 5² of the 2 remaining one-fourth lengths.
