Dear Dr. Wallace.
In reference to the occurrence of abnormally thick coal-seams, referred to when we met in the train on Friday last. I have now looked up my notes & find that in 1891 I obtained the following information:— Mr William Warren, an engineer, drew attention to important seams of anthracite in the hills fringing the Gulf of Tonquin. One of the seams is 152 ft. thick, & contains 87% of carbon[?]. The coal has since been successfully tried in the steamer <Falsleau?>, & I believe the French have now a coaling station there.
The other case to which I referred, & where there is a seam 180 ft. thick, is at the coal mines of Hatu, near Hongai, on the Bay of [H]Along. See "Journeys in French Indo-China", by <Hon.> G.N. Curzon, Geog. Journ. Sept 1893 pg. 198.
I do not think we can doubt the conclusions arrived at by these observers.
Yours very truly

P.S. Personally I don't understand it.
