CHALK. Carbonate of lime, contains 

 when pure Carbonic acid, 45 ; lime, 55. 

 But as it usually occurs it contains about 

 twenty-four per cent, of water, and five 

 per cent, of silica (flint), alumina (clay), 

 and oxide (rust) of iron. After these 

 deductions it will be apparent that if 

 fifty tons of lime be applied to land, it 

 will be equal to more than one hundred 

 of chalk, a subject worthy of considera- 

 tion when it has to be conveyed from 

 afar. Chalk is usually employed in 

 large quantities to improve the staple of 

 a soil. It makes heavy soils less reten- 

 tive of moisture, and light sandy soils 

 more retentive. On wet sour lands it 

 neutralizes the acids which render them 

 unproductive. Some chalks contain 

 phosphate of lime, and this being a con- 

 stituent of all plants, such chalk is to be 

 preferred. Some contain a large pro- 

 portion of carbonate of magnesia, which 

 is less beneficial. Chalk has also been 

 shown by Mr. Beaton to be of great value 

 in forming the best of walks. See Con- 

 crete Walks.

 gamia, 2-dieecia). Seed's, imported; suck- 

 ers which are freely produced, with the 

 exception of C. gracilis and gttiammis, 

 the others will flourish in a greenhouse, 

 and their leaves render them striking 

 objects. In Edinbtirgh the Jmmilis stood 

 out several winters, with but a slight 



Iberia. 18
