The Detroit Journal contains a letter from Dr. Houghton dated La Pointe, Lake Superior, June 21st, when mention that during the past winter a band of Muskegons or Mountaineers, speaking a dialect of the Chippewa language, fell upon a trading post situated on the Napagon River, belonging to the Hon. Hudson Bay Company, and murdered, indiscriminately all the traders occupying the post. This induced the Company to collect their forces from different posts, and to send them against the band of Indians. An action took place, in which twenty traders and Indians were killed. The difficulties still remain unsettled.
