the greatest mountain of the country.  This is known by the name of Paganet, and lies to the southwest of Lake Matapediac, forming a part of the highlands which are so obviously described as the boundary of the Province of Quebec in the proclamation of 1763.  Its height was reported to be probably 3,000 feet, but as it has appeared in the course of the survey that heights in that region may easily be overestimated, it can not be safely taken at more than 2,500 feet.  The result of the astronomic observations seemed to show that the main stream would lead too far to the eastward, and after mature deliberation it was resolved that the course should be retraced and the Mistigougeche ascended.  The first part of the operation was attended with little delay.  Half an hour sufficed for reaching the forks, whence the party had been six hours in mounting.  The guide also stated that the Mistigougeche was a much less difficult stream than Metis.  Of the comparative facility, except for a few miles of the latter, no opportunity for judging was obtained; but these were so difficult as to confirm his statement.  On the other hand, the former was found to be much worse than it had been represented by him.  His knowledge, in fact, was limited to its state in winter, for it appeared from a subsequent interview with Captain Broughton to be doubtful whether he had served in the employ of that officer; and it can be well imagined that the river when locked up in ice should present an aspect of far less rapidity than when rushing with its springtide violence.  The Mistigougeche was found to be intercepted by a fall of a few feet, which could not be passed by the boats when loaded, although the Penobscot men boldly and successfully carried theirs up when empty, in which feat they were imitated by the voyageurs, who had at first deemed it impossible.  The loads of the boats were carried over a portage, and in this operation the chronometers were found to deviate from each other, showing a manifest change of rate in some or all of them.  This may be ascribed to a change in the mode of transportation, but was more than could be reasonably anticipated, considering the shortness of the portage (2,000 yards) and the great care that was taken in conveying them.  At some distance above the falls a lake of moderate size was reached, embosomed in hills and embarrassed at its upper end with grass.  From the last feature it was ascertained that both lake and river take their epithet of Grassy (Riviere an Foin, and, in Indian, of Mistigougeche, or Grassy Lake).  At this lake the party of the commissioner was in advance of the loaded boats.  A halt was therefore made and a party sent out to explore to the westward.  This party reached an eminence whence a lake was seen, which the guide stated to be the head of a branch of the Rimouski, far distant, as he averred, from any waters of the Restigouche.  Subsequent examination has shown that this party had actually reached the height of land and that the survey of the boundary might have been advantageously commenced from this point.
