tVesh water, placed in wooden vessels ; care being taken to keep 

 it covered with the liquid, which is changed no less than live 

 times in the course of the day. If it can be changed at night 

 as well, it is all the better for it, the object being to let it 

 imbibe the water gradually and equally. When it is quite 

 soft, but before it turns sour, it is passed through linen cloth, 

 or else wicker-work, after which it is poured out upon a tile 

 covered with leaven, and left to harden in the sun. Next to 

 the araylum of Chios, that of Crete is the most esteemed, and 

 next to that the ^Egyptian. The tests of its goodness are its 

 being light and smooth : it should be used, too, while it is 

 fresh. Cato," among our writers, has made mention of it. 



CUAP. 18. THE NATUKE OF BARLEY. 



Barley-meal, too, is employed for medicinal purposes ; and 

 it is a curious fact, that for beasts of burden they make a paste 

 of it, which is first hardened by the action of fire, and then 

 ground. It is then made up into balls, which are introduced 

 ,vith the hand into the paunch, the result of which is, that the 

 vigour and muscular strength of the animal is considerably 

 increased. In some kinds of barley, the ears have two rows 

 of grains,^ and in others more; in some cases, as many as six.^^ 

 The grain itself, too, presents certain difi'erences, being long 

 and thin, or else short or round, white, black, ^"^ or, in some 

 instances, of a purple colour. This last kind is einployed for 

 making polenta : the white is ill adapted for standing the se- 

 verity of the weather. Barley is the softest of all the grains : 

 it can only be sown in a dr}-, loose soil,*'^ but fertile withal. 

 The chaff of barley ranks among the very best ; indeed, for 

 litter there is none that can be compared with it. Of all grain, 

 barley is the least exposed to accidents, as it is gatliered before 

 the tinui that mildew begins to attack wheat; for which reason 

 it is that the [jrovident agriculturist sows only as much wheat.
