estimated that 600,000 barrels were sent to market from those 

 kilns. It is shipped to all American Atlantic ports and the West 

 Indies. From that period it is almost needless to say that the 

 production of hydraulic cement, in the United States, has im- 

 mensely increased. 



Many of the Canadian beds of water lime appear to be of excellent 

 quality ; they are generally distributed through the country, from 

 the valley of the Grand River to the Sangeen. Trials have been 

 made by Mr. Hunt, on a specimen from near Brantford, which^ 

 in five minutes, set under water. 



OCHRES. 



Ochre used as a paint, is'of growing importance on this conti- 

 nent. So many of our structures are built of wood, that their 

 preservation from the air, and a desire to give them a suitable 

 atid agreeable appearance, naturally leads to their being covered 

 with some material possessing the required properties. Ochres 

 of different tints are larg-ely used for this purpose. Canada im- 

 ports a very considerable quantity of ochre in a manufactured state, 

 and yet possesses within her borders, very extensive and valuable 

 deposists of this mineral. The exhibition of ochres at Montreal in 

 1850 attracted the attention of a stranger, who enquired of Sir W. 

 Logan, where they came from ; he was informed of the position, 

 and of the means of obtaining access to them. The stranger, know- 

 ing the value of the deposit, immediately secured the property 

 on which it was found. In 1852-53 Sir W. Logan relates the 

 subsequent history of this ochre bed, which affords one instance 

 out of hundreds, which have occurred in Canada, of foreigners fa- 

 miliar with the value of some of our natural products, and acquir- 

 ing knowledge of their extent and distribution appropriating, and 

 with perfect justice, the gain to themselves. 



"A very large ochre bed is situated on the St. Nicholas range 

 of Pointe-du-Lac, on the property of Mr. Piere Chaillon and his 

 brother. It is crossed by the range road, running north westward, 

 over a mile from the point where starts from the water-side road ; 

 the deposit extend on each side of the road, about ten acres to 

 the south-west, and forty acres to the north-east ; the breadth is 

 irregular, and varies from one to twenty acres, and the whole area 

 may be about 400 acres ; the thickness of the deposit ranges from 

 six inches to four feet, and may have an average of about eighteen
