THE SUB-ARCTIC ZONE. 41 



Glancing at the map, we find we have reached the eastern 

 limit of this zone, and conclude there is nothing more to be 

 done, at least in this hemisphere. But our labours are 

 not yet at an end. It is true that scarcely any of Kamt- 

 schatka lies in this zone, but its cold climate produces a 

 flora of such a sub-arctic character, that, with the exception 

 of the southern part, Meyen includes it in this region. The 

 trees are nearly the same as those in the Siberian forests : 

 two or three different kinds of Birch ; the Larch, and other 

 Pines; the White Poplar, the Plane, a Willow (Salix pent-

 common Juniper. There is also the Mountain Bramble 

 (Rubus Chamtzmorus] ; and another called Rubus Arcticus ; 

 the Eed Whortleberry (Paccinium Fitis-idcea) , and the Bog 

 Whortleberry ( V. uliginosum] ; the common Barberry (Ber- 

 beris vulgaris), the Eed Currant (Rides rubrum], the com- 

 mon Crowberry (Empetrum nigrum), the Wild Cherry (Pru- 

 nus Padus], the Mountain Ash (Sorbus Aucuparia), and the 

 Eed Bearberry (Arbutus Uva-ursi}. 



It is an agreeable surprise, in this distant land, to meet 

 with Wild Eoses and Honeysuckles, and with another old 

 favourite, the White Thorn, (Rosa spinosissima and Rosa 

 canina, Lonicera ctzrulea and Cratagus Oxyacantha). To
