The Snake Story again.—The following extract of a letter from Gen. Milroy to a gentleman of this place, puts to flight any remaining credulity which may be placed to the credit of (his story. We doubt, indeed, if this will not set at rest even the recent discovery of the Telegraph i. e. that the monster has degenerated into the monster of the U. S. Bank. In other words, that Nick Biddle is the Devil of Lake Man-i-too.“I had noticed the snakc-slory to which ‘‘you refer. It appears to be going the “rounds, and I am unwilling to be referred “to as vouching for the truth of a tale of “this class in which the author has thought“proper to introduce my name. I reraem-“ber of hearing something of an Indian “tradition that doubtless gave rise to this “tale—for myself I never credited it as “reality. You are aware of Indian cre-“dulity, as relates to that which they have “received from their Fathers;—also, how“many residing places they have imagined “for their Man-i-toos,—their good or evil “spirits. All that I learnt relative to the“Lake, that never appears to have received the name of the “Devil’s Lake,” I “suppose had its origin in some such tradition or fiction. So far as came to my“knowledge, the Indians had no fear of “being on the Lake; their fishing and “night-hunting for deer, was common on “it. The objection made by them to the “erection of the mills, was that the dam “at the outlet would injure their fishing.“I will add, that if any are disposed to “invent a “snake-sfory,” I would thank “them not to introduce my name into it; “this class of tales does very well without“a witness.”
