August 11-1921. Thursday. Left St. Albans at 10.15 for the Parkers farm quarry, then the Hurland farm, and now the Montcalm farm. The latter purchased the place last year and are French Canadians from east of Ottawa. This farm is in the north- north-western corner of the Milton Quadrangle, 2 miles north 60 degrees west of Seneca Centre. The largest slate quarry is back in the field near a large elm tree in hard blue slates. Another one is half way up the hillside near the road and two other small slate quarries are beside the road. In the latter we got three backspuds (see list of faces end of this book). in the others we saw nothing. The slate bed has a considerable thickness, probably so far can be seen but apparently there is much more. Above the slate come micaceous, thin-bedded dolomite beneath the ^ that are more crumpled than any of the other rocks. In these occur may iron rock nodules = pure dolomite
