GOITRES.
The following remarks on a well-known disease are extracted from Dr. Richardson’s Journal:
Bronchocele or Goitre is a common disorder at Edmonton. I examined several of the individuals afflicted with it and endeavoured to obtain every information on the subject from the most authentic sources. The following facts may be depended upon. The disorder attacks those only who drink the water of the river. It is indeed in its worst state confined almost entirely to the half-breed women and children who reside constantly at the fort and make use of river water drawn in the winter through a hole cut in the ice. The men, being often from home on journeys through the plain, when their drink is melted snow, are less affected; and if any of them exhibit during the winter some incipient symptoms of the complaint the annual summer voyage to the sea-coast generally effects a cure. The natives who confine themselves to snow-water in the winter and drink of the small rivulets which flow through the plains in the summer are exempt from the attacks of this disease.
These facts are curious inasmuch as they militate against the generally received opinion that the disease is caused by drinking snow-water; an opinion which seems to have originated from bronchocele being endemial to subalpine districts.
The Saskatchewan at Edmonton is clear in the winter and also in the summer except during the May and July floods. This distance from the Rocky Mountains (which I suppose to be of primitive formation) is upwards of one hundred and thirty miles. The neighbouring plains are alluvial, the soil is calcareous and contains numerous travelled fragments of limestone. At a considerable distance below Edmonton the river, continuing its course through the plains, becomes turbid and acquires a white colour. In this state it is drunk by the inmates of Carlton House where the disease is known only by name. It is said that the inhabitants of Rocky Mountain House, sixty miles nearer the source of the river are more severely affected than those at Edmonton. 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 à 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. At three P.M. we parted from our kind host and, in passing through the gate, were honoured with a salute of musketry. After riding six miles we joined the men at their encampment which was made under the shelter of a few poplars. The dogs had been so much fatigued in wading through the very deep snow with their heavy burdens, having to drag upwards of ninety pounds’ weight each, that they could get no farther. Soon after our arrival the snow began to fall heavily and it continued through the greater part of the night.
