"In the evening we saw a Brown or Grisley beare on a sand beech, I went out with one man Geo Drewyer & Killed the bear, which was verry large and a turrible looking animal, which we found verry hard to kill we Shot ten Balls into him before we killed him, & 5 of those Balls through his lights This animal is the largest of the carnivorous kind I ever saw we had nothing that could way him, I think his weight may be stated at 500 pounds [227 kilograms].... we had him skined and divided, the oile tried up & put in Kegs for use."
