The same disease occurs near the sources of the Elk and Peace Rivers; but in those parts of the country which are distant from the Rocky Mountain Chain it is unknown although melted snow forms the only drink of the natives for nine months of the year.
A residence of a single year at Edmonton is sufficient to render a family bronchocelous.

Many of the goitres acquire great size.

Burnt sponge has been tried and found to remove the disease but an exposure to the same cause immediately reproduces it.
A great proportion of the children of women who have goitres are born idiots with large heads and the other distinguishing marks of cretins.

I could not learn whether it was necessary that both parents should have goitres to produce cretin children: indeed the want of chastity in the half-breed women would be a bar to the deduction of any inference on this head.

DEPARTURE FROM CARLTON HOUSE.
February 8.
Having recovered from the swellings and pains which our late march from Cumberland had occasioned we prepared for the commencement of our journey to Isle a la Crosse, and requisitions were made on both the establishments for the means of conveyance and the necessary supply of provisions for the party which were readily furnished.

On the 9th the carioles and sledges were loaded and sent off after breakfast; but Mr.
Back and I remained till the afternoon as Mr.Prudens had offered that his horses should convey us to the encampment.
