D , 114° 12' 35" W. From this circumstance, it is obvious that the observations then obtained, of O W. !) , could not, with any regard to accuracy, be used with those procured on the opposite side in the autumn of 1820. Advantage was taken of every opportunity to ascertain the rates of the chronomer ters, during the descent of the Copper-Mine River, and in the subsequent journey along the coast ; and whenever we were assured, by good observations, of their hav- ing altered, a correction was the...n made. At other times, their rate of going was usually seen by comparison with 1733. On the return of the Expedition to Wilberforce Falls, the chronometers were found to have altered their rates so much, as to give the longitude of the first cascade in Hood's River forty miles westward of what they had done twenty-four days before. Other rates having been procured during our stay near these Falls, a proportional allowance was made, to be applied to the results of all the observations by the chro- nometers, between Goulburn's Islands and Point TuTnagain.
