Alexander Winchell,
Notice of the Remains of a Mastodon recently discovered in Michigan
(1864)
“ Indeed, the watery and shaking condition of this bog, with the thinness of the peaty stratum, furnish data for the belief that it was the bed of a lakelet within a comparatively short period. It is much more credible that the Mastodon under consideration was living within 500 or 1000 years, than that an interval of time, greater than the age of the human race, has been occupied in the accumulation of two or three feet of vegetable deposits, under circumstances which suffer the same work to be accomplished, in neighboring localities, within the space of a human life-time. ”
