Mitchell's Cove.--In the town of Canajoharie, Montgomery county, near the summit of a precipitous, rocky mountain, called "The Nose," on the south bank of the Mohawk river, there has lately been discovered, and partially explored a remarkable cave, of which a particular account was published in the Johnstown Republican of the 11th ult. Dr. Barlow and 15 or 16 other gentlemen visited this cave on the 4th of July. They descended by a rope about 16 feet to a room 11 feet by 30, about 19 feet high and arched. At the extremity of this room they found a narrow passage; through this passage, which is about 20 feet long, they entered a second room more spacious than the first They thence descended at various angles with the horizon, through narrow passes, from room to room, till they reached in regular succession the tenth apartment. besides several lateral rooms, leading out of these several apartments.

They supposed the whole depth of their descent was more than 500 feet; and much of the cavern probably remains unexplored. Innumerable stalactites are suspended from the ceiling of the rooms, and from the projecting rocks in the walls. The mouth of the cave is about 40 chains south of the line of the Erie canal.
