At the foot of this lake, which is between twenty and thirty miles long, the east branch of the St. Croix takes its rise. From this point it passes through a rocky channel for the most part, occasionally flowing through a section of meadow or intervale land until it reaches Baring, a distance of some fifty miles, where for the first time it meets with a formidable barrier to its hitherto wild and unrestrained progress in the character of a "_dam_." Passing this through its various avenues, it flows on to Milltown, which occupies both sides of the river, and includes both the English and American villages. Between this place and the head of ship navigation, some two miles distant, the channel is _dammed_ several times on a succession of falls, where are numerous saw-mills; and, finally, after having leaped a thousand rocky precipices above, and struggled through as many gates and sluice-ways below, it quietly flows on to the Passamaquoddy Bay, where its restless waters find repose in the bosom of the Atlantic Ocean. In regard to the lumbering resources on this river, I believe it is generally admitted that the supply of Pine is comparatively small, the principal part having already been brought to market; and although the territory belonging to this river is large, still its resources are curtailed by the proximity of the head waters of the St. John, Penobscot, and Machias Rivers. The comparative scarcity of Pine timber has induced the manufacture of a much larger proportion of Spruce than formerly; still it is presumed that the same amount of Pine lumber now annually cut may continue to be for years to come. Should Hemlock come into more general use, the resources of the lumbermen will be greatly augmented, as timber of this kind abounds on the St. Croix. And why may not this be the case? For many purposes Hemlock lumber is preferred to Pine. A gentleman in Bangor informed the writer that he had, from choice, made use of Hemlock boards for nice floors to a residence recently built for himself, esteeming it richer in color, less liable to indentation, and of greater durability. With the exception of _Pine_, the resources for lumber on this river are still very considerable, and must continue to be for many years, unless sweeping fires shall blacken and wither the beautiful forests which now adorn the interior. Vast tracts of timber land have already been destroyed by fire on the territory belonging to this river, as the blanched trunks of standing trees, and barren hill country surrounding Baileyville, Baring, Calais, and St. Stephen's, most painfully indicate, greatly marring the beautiful scenery which once adorned the valley through which the river flows.
