East View of Lowell - The engraving shows the central part of Lowell as it appears from the high ground on the eastern bank of the Merrimac, over which is seen the central bridge. The mouth of Concord River is on the left. The Middlesex Woolen Factory appears on the extreme left; the Prescott Mills next northward. The Massachusetts Mills extend from this point to the bridge. The next westward are the Boott and the Merrimac Mills. The Lawrence Mills are still farther westward, but not embraced in the view.
