166 ALLIGATOR MIRAGE. 



of several thousand cows, they asked in vain for 

 milk, and were obliged to content themselves with 

 some muddy and fetid water drawn from a neigh- 

 bouring pool, of which they contrived to drink by 

 using a linen cloth as a filter. When the mules 

 were unloaded, they were set at liberty to go and 

 search for water, and the strangers following them 

 came upon a copious reservoir surrounded with palm- 

 trees. Covered with dust and scorched by the sandy 

 wind of the desert, they plunged into the pool, but 

 had scarcely begun to enjoy its coolness when the 

 noise of an alligator floundering in the mud induced

 selves in all their modifications. The little currents 

 of air that passed along the ground had so variable a 

 temperature, that in a herd of wild cows some ap-

 suspended, but no inversion was observed. At sun- 

 rise the plains assumed a more animated appearance ; 

 the horses, mules, and oxen, which graze on them 

 in a state of freedom, after having reposed during the 

 night beneath the palms, now assembled in crowds. 

 As the travellers approached Calabozo they saw 

 troops of small deer feeding in the midst of the 

 cattle. These animals, which are called, matacani,
