_Four_ of the giant brood with ILEX stand,
Each grasps a thousand arrows in his hand;


[_Ilex_. l. 161. Holly. Four males, four females. Many plants, like many
animals, are furnished with arms for their protection; these are either
aculei, prickles, as in rose and barberry, which are formed from the
outer bark of the plant; or spinæ, thorns, as in hawthorn, which are an
elongation of the wood, and hence more difficult to be torn off than the
former; or stimuli, stings, as in the nettles, which are armed with a
venomous fluid for the annoyance of naked animals. The shrubs and trees,
which have prickles or thorns, are grateful food to many animals, as
goosberry, and gorse; and would be quickly devoured, if not thus armed;
the stings seem a protection against some kinds of insects, as well
as the naked mouths of quadrupeds. Many plants lose their thorns by
cultivation, as wild animals lose their ferocity; and some of them
their horns. A curious circumstance attends the large hollies in
Needwood-forest, they are armed with thorny leaves about eight feet
high, and have smooth leaves above; as if they were conscious that
horses and cattle could not reach their upper branches. See note on
Meadia, and on Mancinella. The numerous clumps of hollies in
Needwood-forest serve as landmarks to direct the travellers
across it in various directions; and as a shelter to the deer and cattle
in winter; and in scarce seasons supply them with much food. For when the
upper branches, which are without prickles, are cut down, the deer crop
the leaves and peel off the bark. The bird-lime made from the bark of
hollies seems to be a very similar material to the elastic gum, or Indian
rubber, as it is called. There is a fossile elastic bitumen found at
