NO. 2 BIBLIOGRAPHY OF TIN HESS 105 



LAOS (Continued) 



Mine located in Province of Kammun, Laos, in a small tributary valley of the Hin- 

 bun River. At present worked by French, has long been worked by natives. Ore 

 occurs in limestone, no eruptives. Not in place, but little water worn. None of the 

 ordinary minerals accompanying tin are present. Cassiterite often resembles " needle 

 ore " of Cornwall. Cassiterite supposed to be a primary constituent of a sulphide 

 gossan, as at Carnpiglia, Italy.

Copper and tin ores are mined in a small way. So far these ore deposits do not 

 seem very extensive or rich. Some tin is exported.

The analysis of a specimen from Antananarivo gave 77.5 per cent metallic tin, but 

 it is scarcely to be expected that when mined on a large scale such a high content 

 of metallic tin will be maintained.

Tin has long been* known to exist in region of Ambatofangehana, and recently tin 

 has been found in the southern part of the district of Ambohimanga.

States that tin ore at Mt. Mica, Paris, Maine, is in "a very coarse granite, in a 

 finer granite, and this cuts a coarse mica schist, the oldest rocks in Oxford Co." 

 " Largest known cut tourmaline in the world came from this hill, and is valued at 

 300. It is owned by Prof. C. U. Shepard of Amherst College." A crystal of 

 cassiterite exceeding 5 pounds in weight had been taken out. Thinks the deposit 

 and the one at Mt. Rubelite, in Hebron, worth exploring.

Short article recording a recent discovery of tin ore at Winslow, Maine. The 

 inclosing rock is described as a mica slate, adjacent to which is a hard quartzite 

 band. Author states that mineralogical, geological, and physical features are 

 identical with those common to the stanniferous districts of Europe.
