This porous pottery for keeping water cool had been imported from America, and was chiefly made in Andalusia, Portugal, and Extremadura. It is still produced at Andujar and elsewhere. Nearly all travellers in Spain describe it, and insist upon the curious circumstance that it was eaten by the Spanish women. "I have mentioned elsewhere," wrote Countess d'Aulnoy, "the longing many women feel to chew this clay, which often obstructs their bodies internally. Their stomachs swell, and grow as hard as stone, while their skin turns yellow as a quince. I also felt a curiosity to taste this ware, that is so highly yet so undeservedly esteemed; but I would devour a grindstone rather than put it in my mouth again. Nevertheless, if one wants to be agreeable to the Spanish ladies, one has to present them with some _bucaros_, which they themselves call _barros_, and which, as many deem, possess such numerous and admirable qualities, since they claim for the clay that it cures sickness, and that a drinking vessel made of it betrays the presence of a poison. I possess one which spoils the taste of wine, but greatly improves water. This liquid seems to boil and tremble when it is thrown into the cup in question; but after a little while the vessel empties--so porous is the clay of which it is composed--and then it has a fragrant odour." Similar accounts are given by travellers of a later time. "I wish," wrote Swinburne, "I could contrive a method of carrying you some of the fine earthen jars, called _buxaros_, which are made in Andalusia. They are remarkably convenient for water-drinkers, as they are light, smooth, and handy; being not more than half-baked, they are very porous, and the outside is kept moist by the water's filtering through; though placed in the sun, the water in the pots remains as cold as ice. The most disagreeable circumstance attending them is, that they emit a smell of earth refreshed by a sudden shower after a long drought."[92] [92] _Travels through Spain_; p. 305. Swinburne could have been no lover of nature to speak in such terms of the smell of earth.
