AGRICULTURE. 33 



Crossing may be attended Avith bad effects, even 

 when begun on good principles, if the above rule be 

 attended to throughout; for instance, if large ewes 

 were brought to Wales, and sent to the rams of the 

 country, the offspring would be of improved form; and 

 if sufficiently fed, of a larger size than the native ani- 

 mals, but the males of the breed would be dispropor- 

 tionately large to the native ewes, and therefore would 

 produce a starveling ill formed race with them. 



The general mistake in crossing has arisen from an 

 attempt to increase the size of the native race of ani- 

 mals; being a fruitless effort to counteract the laws of 

 nature; which from theory, from practice, and extensive 

 observation, Mr. Cline, concluded to be decidedly wrong; 

 for in proportion to this unnatural increase of size, they 

 become worse in form, less hard}', and more liable to 

 disease. 



Tlie Massachusetts Agricultural Repository, vol. vi. 

 p. 78, contains some valuable remarks on the subject 

 of "Dairy Stock," by S. W. Pomeroy, Esq. We shall 

 give the following extract, which presents an important 

 fact, not sufficiently known or attended to by writers 

 who have treated on the same or similar subjects, 



"In the selection of bulls, most farmers confine their 

 attention to form and colour only, instead of tracing 

 their descent to a valuable dairy stock. It has been 

 observed by Linnasus that those properties of animals 

 which relate to the vessels, or in scientific terms, the cor- 

 tical substance, or vascular sifstem, are derived from the 

 males^'' and among other examples tending to confirm 

 this opinion, he states "that a cross from the male An- 

 gora goat, with the common female goat produces that 

 fine wool or substance, called Camel's hair; but .that the 

 progeny from the male common goat with the female 

 Angora, is productive of nothing but the same Avorthless 

 hair of the sire." 



TO SELECT GOOD LAND FOR FARMING. 



The remark will, at first view, strike most persons as 

 a kind of contradiction in terms, that the very richest 

 land is not that on which Farmers have the best success,
