The Desert Pampas.

What a blessed thing it would be for poor rabbit- 
worried Australia if a similar plague should visit 
that country, and fall on the right- animal ! On 
the other hand, what a calamity if the infection, 
wide-spread, incurable, and swift as the wind in its 
course, should attack the too-numerous sheep I 
And who knows what mysterious, unheard-of retri- 
butions that revengeful deity hTature may not be 
meditating in her secret heart for the loss of her

little cavy’s habits, and the habits of all cavies, I 
fancy, are not so well suited to the humid grassy 
region as to other districts, with sterile ground to 
run and play upon, and thickets in which to hide. 
A more interesting animal is the Ctenomys 
magellanica, a little less than the rat in size, with 
a shorter tail, pale grey fur, and red incisors. It 
is called tuco4uco from its voice, and ocidto from its 
habits ; for it is a dweller underground, and re-

may surim beneath the surface. Consequently the 
pampa, with its heavy, moist mould, is not the 
tuco’s proper place; nevertheless, wherever there
