SCIENCE OF GARDENING. 



PART II. 



taining equal parts of clay, lime, and sand, would, as a generic term, be called clay, 

 lime, and sand; if it contained no other mixture in considerable quantity, the term 

 entire, might be added as a specific distinction ; and if notice was to be taken of its color 

 or degree of comminution, it might be termed a brown, a fine, a coarse, a stiff", or a free 

 entire clay, lime, and sand. 



1034. The following Table enumerates the more common genera, species, and varieties of 

 soils. The application of the terms will be understood by every cultivator, though to 

 attempt to describe the soils either chemically, or empirically (as by sight, smell, or touch), 

 would be a useless waste of time. From a very little experience in the field or garden, 

 more may be gained in the study of soils, than from a volume of such descriptions. Tliis 

 table corresponds with the nomenclature adopted in the agricultural establishments 

 of Fellenberg at Hofwyl in Switzerland, of Professor Thaer at Mcegelin in Prussia, of 

 Professor Thouin in his leatures at Paris, and in general with that of all the 

 continental professors. It is therefore very desirable that it should become as generally 

 adopted as that of the Linnaean system in botany. The principle of the table may be 

 extended so as to include any other soil whatever.
