Loam denotes any foil moderately cohefive, that is, lefs fo than 

 clay, and more fo than loofe chalk ; by the author of the body 

 of agriculture it is faid to be a clay mixed with fand. Dodlor 

 Hill defines it an earth compofed of diffimilar particles, hard, 

 ftiff, denfe, harfli and rough to the touch, not eafily dudlile 

 while moift, readily difFufible in water, and compofed of 

 fand and a tough vifcid clay. The definition I have given 

 feems mofl fuited to the different fpecies I fliall now enumerate. 



Clayey Loam denotes a compound foil, moderately cohefive, 

 in which the argillaceous ingredient predominates. Its cohe- 

 rence is then greater than that of any other loam, but lefs 

 than that of pure clay ; the other ingredient is a coarfe fand, 

 with or without fmall mixture of the calcareous ingredient. 

 It is this which farmers generally call Jirojig, Jllff^ cold and 

 heavy loam, in proportion as the clay abounds in it. 



Chalkey Loam. This term indicates a loam formed of clay, 

 coarfe fand and chalk, in which, however, the calcareous 

 ingredient or chalk much predominates. It is lefs cohefive 

 than clayey loams, 



Sandy Loam denotes a loam in which fand predominates j 

 It is lefs coherent than either the abovementioned. Sand, partly 

 coarfe and partly fine, forms from 80 to 90 per cent, of this 

 compound. 



Gravelly Loam differs from the laft only in containing 

 a larger mixture of coarfe fand or pebbles. This and the two 



laft
