Falklands, etc.] FLORA ANTARCTICA. 387 



who thus became, first the injurer, and then the protector and propagator of the existence of this noble grass ; for the 

 herbivorous quadrupeds which he carried to the Falklands and left there, were surely extirpating the Tussock, when 

 man returned, and, by protecting, perpetuating, and transporting it to other countries, he has widely dispersed it. 

 It appears singular that so striking a grass should abound where there is no native herbivorous animal to profit by 

 its luxuriance ; but it is no less certain that had not civilization interfered, the Tussock might have waved its green 

 leaves undisturbed over the waters of the stormy Antarctic Ocean, for ever perhaps, or until some fish, fowl, or 

 seal, should be so far tempted by the luxuriance of the foliage as to transgress the laws of nature, and to adapt its 

 organs to the digestion and enjoyment of this long-neglected gift of a bounteous Providence. 



It must appear strange to all who know grasses oidy in the pastures of England, that the patches of Tussock 

 resemble nothing so much as groves of small low Palm-trees ! This similarity arises from the matted roots of the 

 individual plants springing in cylindrical masses, always separated down to the very base, and throwing out a waving 

 head of foliage from each summit. Bogs and damp woods in Britain very frequently produce a Sedge (Carer 

 paniculata), whose mode of growth is, on a small scale, identical with that of the Tussock-Grass, and to which the 

 name of Tussock is applied. I have seen them two to three feet above the ground, in South Wales ; and if they 

 were higher, larger, and placed closer together, the general resemblance would be complete. The effect in walking 

 through a large Tussock grove is . very singular, from the uniformity in height of these masses, and the narrow 

 spaces left between them, which form an effectnal labyrinth ; leaves and sky are all that can be seen overhead, 

 and their curious boles of roots and decayed vegetable matter on both sides, before and behind ; except now and 

 then, where a penguin peeps forth from his hole, or the traveller stumbles over a huge Sea-lion, stretched along the 

 ground, blocking up his path.
