tremendous strain that had been brought to bear, to fault the entire forniation, 

 and shatter the rock on either side of it. The core from the diamond drill showed 

 all the base metals to be present in this cross lode, and every indication of its 

 being a finely mineralized lode and one that can be expected to be a laige pro- 

 ducer of the precious metal. This cross lode is lying on a very flat dip east. 

 About all the 52 lodes found, showed good base metal in the drill core, but as the 

 core was only | of an inch in diameter, there was not much chance of striking gold.

The Recording Secretary read a letter from Rev. M. Maury, D. D. , of Walt - 

 ham, Mass., Corresponding Member of the Institute, containing a suggestion as 

 to the cause of the differences of colour in Granite rocks, as follows : — 



" Visiting a pottery in the town of Keene, N.H., I was told of an establishment 

 in which granite is moulded and made into tiles, building stones, ornamental 

 pieces, &c., &c. The moulding of granite appearing to involve an incongruity, I 

 wended my way toward the ' Keene Granite Terra Cotta and Tile Works ' where 

 I saw the mystery satisfactorily solved. 



" An objection to granite as a building stone is the fact that it will not stand 

 heat. Subjected to heat it loses its tenacity and becomes brittle. Of this property 

 advantage is taken in the manufacture of moulded granite. Ten tons of the 

 crude stone are placed at once in a kiln and heated with a wood fire — the process 

 being altogether similar to the burning of lime. When taken from the kiln the 

 granite will crumble. It is easily reduced to the condition of sand. The next 

 features of the process are identical with those of the manufacture of tiles. The 

 sand-like granite is intimately mixed in water with clay, pulverized ;'elspar and 

 silica, forming what the tilemaker knows as ' paste,' which closely resembles in
