I remember meeting a distinguished man in India, who had the reputation of being a great shikaree, who told me that the greatest temptation he had ever had in his life was to shoot a giant snake which he had come across in the Terai of Upper India. He was on a tiger-shooting expedition, and as his elephant was crossing a nullah, it squealed. He looked down from his howdah and saw that the elephant had stepped across the body of a snake which was dragging itself through the jungle. 'So far as I could see,' he said, 'it must have been eighty or one hundred feet in length.
Fully forty or fifty feet was on each side of the track, and though the weight which it dragged had thinned it, it was as thick round as a man's body. I suppose you know that when you are after tiger, it is a point of honour not to shoot at anything else, as life may depend on it. I could easily have spined this monster, but I felt that I must not--so, with regret, I had to let it go.'
"Just imagine such a monster anywhere in this country, and at once we could get a sort of idea of the 'worms,' which possibly did frequent the great morasses which spread round the mouths of many of the great European rivers.""I haven't the least doubt, sir, that there may have been such monsters as you have spoken of still existing at a much later period than is generally accepted," replied Adam. "Also, if there were such things, that this was the very place for them. I have tried to think over the matter since you pointed out the configuration of the ground. But it seems to me that there is a hiatus somewhere. Are there not mechanical difficulties?""In what way?"
"Well, our antique monster must have been mighty heavy, and the distances he had to travel were long and the ways difficult. From where we are now sitting down to the level of the mud-holes is a distance of several hundred feet--I am leaving out of consideration altogether any lateral distance. Is it possible that there was a way by which a monster could travel up and down, and yet no chance recorder have ever seen him? Of course we have the legends; but is not some more exact evidence necessary in a scientific investigation?""My dear Adam, all you say is perfectly right, and, were we starting on such an investigation, we could not do better than follow your reasoning. But, my dear boy, you must remember that all this took place thousands of years ago. You must remember, too, that all records of the kind that would help us are lacking. Also, that the places to be considered were desert, so far as human habitation or population are considered. In the vast desolation of such a place as complied with the necessary conditions, there must have been such profusion of natural growth as would bar the progress of men formed as we are. The lair of such a monster would not have been disturbed for hundreds--or thousands--of years. Moreover, these creatures must have occupied places quite inaccessible to man. A snake who could make himself comfortable in a quagmire, a hundred feet deep, would be protected on the outskirts by such stupendous morasses as now no longer exist, or which, if they exist anywhere at all, can be on very few places on the earth's surface. Far be it from me to say that in more elemental times such things could not have been. The condition belongs to the geologic age--the great birth and growth of the world, when natural forces ran riot, when the struggle for existence was so savage that no vitality which was not founded in a gigantic form could have even a possibility of survival. That such a time existed, we have evidences in geology, but there only; we can never expect proofs such as this age demands. We can only imagine or surmise such things--or such conditions and such forces as overcame them."
