These divisions must not be taken as hard-and-fast lines of difference, for the edges 

 of the zones necessarily merge gradually one into another. Examples of the 

 characteristic vegetation of one zone may often be seen in the middle of the next, and 

 there is always a difference between the altitudes of the zones as observed in valleys or 

 on exposed ridges. Again, it must not be thought that the particular plants named 

 constitute the sole vegetation of the zones ; they are merely taken as the most 

 conspicuous and characteristic species of certain altitudes. It was most unfortunate 

 and disappointing that the Expedition was prevented from making systematic collec- 

 tions on the west side ; there is so little material from tliat locality that a comparison 

 of the two sides is at present impossible. Although only a few of the birds were 

 obtained on the west side, we saw and heard enough to enable us to say that all or
