38 NOTES. 



235 Near Falmouth, 50 in 100 parts of what is called shelly sand, consist of 

 broken coral. In Cornwall, on the other hand, from 70 to 80 parts in ]00 

 consist of broken shells. The farmers prefer taking it as near low -water mark 

 as possible, for thus they obtain a small quantity of saline matter, (perhaps from 

 3 to 4 or 5 Ibs.) 



The advantages of these calcareous substances as a manure are, ]. That it 

 thickens, or deepens the staple of the soil ; 2. That some parts of the calcareous 

 matter, where it is required, enters into the composition of the plant ; and, 

 5. That it loosens the earth, and rendering it more friable, the plant is thence 

 enabled to take a greater range in quest of food. Communication from the Rev- 

 Robert Hoblyn.

237 It is certain, that in several cases soapers' waste has been found of use ; 

 but it is said to have been extensively tried in Surrey and Kent, upon both old 

 meadows, and arable land, of the stronger kind, without its producing any be- 

 neficial effect. Perhaps it was applied in too small quantities. 



238 Sir Humphry Davy's Lectures, p. 287. The indifferent success which 

 lias attended the trials of gypsum in Derbyshire, where this substance is dug 

 in large quantities, may be owing to its being burnt. Mr Farey therefore, re- 

 commends trying it ground, or in powder, as practised in America, and on the 

 Continent of Europe. Derbyshire Report, vol. ii. p. 448. This substance 

 unburnt, was tried at Holkham, in 1819, for clover and sainfoin, and six bushels 

 of the powder were used per acre, with prodigious effect.

242 In a letter published in the Farmer's Journal of the 13. Dec. 1819, 

 signed John Day, the use of clay ashes is much recommended, as calculated at 

 some future period, to double the value of all the strong clay soils in the Uni- 

 ted Kingdom, by exchanging them from a tenacious clay, to a friable garden 

 mould.

 Ireland.

245 General Report of Scotland, vol. ii. p. 530. This may arise from its 

 being so strongly impregnated with saline matters. It is desirable, however, 

 to have the mud applied as manure, fermented with dung, to destroy all vege- 

 tative powers in the roots, or in the seeds of weeds which the mud might con- 

 tain.

249 Communication from Mr Farey. 



250 The late Duke of Richmond found lime and sea-weed a most excellent 

 compost. He mixed six waggon loads of sea-weed, with one load of lime 

 shells, in a heap 18 feet long and 10 feet wide, in the beginning of August, 

 and in the September following, the compost was carried to the land, turned 

 over three times, and used as a top-dressing in October, when the wheat was 

 sown. The crop exceeded five quarters per acre. The compost had the ap- 

 pearance of earth and lime mixed together, with some streaks of white, which 

 were very salt. The bulk was reduced one-third. 



251 General Report of Scotland, vol. ii. p. 528. Beans and pease thrive 

 well, in a dry season, with ware as a manure ; and it is used in East Lothian 

 for a potatoe crop, with decided benefit.
