In this case we can clearly see that if we wished in imagination to give the plant the power of increasing in number, we should have to give it some advantage over its competitors, or over the animals which preyed on it.
Every being, which during its natural lifetime produces several eggs or seeds, must suffer destruction during some period of its life, and during some season or occasional year, otherwise, on the principle of geometrical increase, its numbers would quickly become so inordinately great that no country could support the product.
The amount of food for each species of course gives the extreme limit to which each can increase; but very frequently it is not the obtaining food, but the serving as prey to other animals, which determines the average numbers of a species.
When a species, owing to highly favourable circumstances, increases inordinately in numbers in a small tract, epidemics--at least, this seems generally to occur with our game animals--often ensue: and here we have a limiting check independent of the struggle for life.
Von Horn, possibly intentionally, misinterpreted the other's motive, and raising his bull whip struck Number Thirteen a vicious cut across the face, at the same time levelling his revolver point blank at the broad beast.
Number Thirteen knew nothing of the danger of firearms, but the noise had startled him and his experience with the stinging cut of the bull whip convinced him that this other was some sort of instrument of torture of which it would be as well to deprive his antagonist.
Again Number Thirteen translated the intent without understanding the words, and releasing von Horn permitted him to rise.
Now in Number Thirteen's brief career he had known no other authority than Professor Maxon's, and so it was that when his master laid a hand upon his wrist he remained beside him while another walked away with the lovely creature he had thought his very own.
We took from them three horses, and all their baggage; and being informed, by two of our number that went to their town, that the Indians had entirely evacuated it, we proceeded no further, and returned with all possible expedition to assist our garrison against the other party.
On the eighth, the Indian army arrived, being four hundred and forty-four in number, commanded by Capt.
During this dreadful siege, which threatened death in every form, we had two men killed, and four wounded, besides a number of cattle.
Harrod proposed to mount a number of horse, and furiously to rush upon the savages, who at this time fought with remarkable fury.
