is foimd to be indispensably iiecessary. Oats mixed with 

 beans or pease, is the grain generally given, although, when 

 barley is at a certain price, it would be an obje<Sl of ceco- 

 nomy to make use of it in lieu of oats. The horses in 

 Spain and Portugal are exclusively fed with barley, to 

 which they give a preference. 



To shew that this taste is not peculiar to foreign 

 horses, it is a well known fadl, that when Burgoyne's 

 regiment of light dragoons went to Portugal in the year 

 J761, the oats sent from England were carefully reserv- 

 ed for the oi")cning of the campaign, and in the mean 

 time the horses were supplied with barley, of which 

 they became so fond, that when the campaign began, 

 they rejected the English oats, and were afterwards uni- 

 formly fed with barley ; notwithstanding which, it will 

 be no easy matter to eradicate the prejudice in favour of 

 oats from the minds of English grooms, which can only 

 be effected by adlual trials and experiments, made by the 

 intelligent, who will afterwards decide for themselves. 

 The different proportions of meal, or farinaceous matter 

 contained in barley and in oats, ought not to pass un- 

 noticed.
