936 THE ADVENTURES OF 



to penetrate into the cave without further delay. He 

 scarcely gave himself time enough to eat, and scolded 1'En- 

 cuerado for being so slow, which was an indirect mode of 

 asking us to hurry. 



'Having again reached the forest, we searched for a pine 

 or a fir, the branches of which, being full of resin, would 

 have enabled us to show more mercy to the moles. Hear- 

 ing us mention these two trees, Lucien wanted to know the 

 difference between them. 



"They both belong to the Coniferous family," replied 

 Sumichrast ; " but firs generally grow upon lofty mountains

Sumichrast' s explanation still left much wanting ; I saw 

 this from Lucien's numerous questions ; but without seeing 

 a specimen of each tree it would have been difficult to bet-

After a long and unsuccessful walk, we halted in front of 

 a guaiac-tree with dark-green foliage, a higher tree than any 

 we had before met with. This fine member of the Ruta-

 would have blunted our weapons, induced me to pass it by. 

 A little farther on, PEncuerado spied out a liquid-amber

 pieces, after I had cleared off their leaves. Our work was 

 interrupted by the approach of night, and we made our 

 way to our bivouac, each loaded with a heavy fagot. 



As soon as we arrived, Lucien had the satisfaction of try-
