72 NOTES OF A NATURALIST. 



occasional loose blocks of stone. The struggles of 

 the few laden animals that we saw in passing, as they 

 toiled along this weary track under a scorching sun, 

 suggested a thought of the wonderful changes which 

 modern inventions have already effected, and are 

 destined to effect in the future, throughout every part 

 of the world. The track before our eyes was, until 

 the other day, the sole line of direct comniunication

 drawbacks for ordinary travellers, is admirably suited 

 to a naturalist in a new country. No time is lost in 

 opening and shutting doors. Standing ready on the 

 platform, one jumps off at every stoppage of the train,

 interested by iinding here some representatives of 

 genera that extend to the hotter and drier parts of 

 the Mediterranean region, such as Boerhavia and 

 Lippia.
