be taught reading, writing, arithmetic, linear drawing, and various 

 useful precepts on industry and the arts. A school for three hun- 

 dred girls, of a similar age, will be added for instruction in literature 

 and needle work. To these are to be added, an adult school for two 

 hundred and fifty of each sex, who have not enjoyed the benefit of 

 early or primary instruction. Finally, on the Sabbath, a school is to be 

 opened for those who are occupied during the week in manual labor. 

 In this quarter of Paris, there is a greater proportion of poor than 

 in any other, and it has been found, that among these suffering class- 

 es, the mortality is much greater than in other parts of the city. In 

 the rich quarters of Faubourg St. Honore, and La Chaussee d'Antin, 

 the deaths annually are one in forty four of the whole number of 

 inhabitants, while in the faubourgs Saint-Jacques and Saint-Marceau, 

 the deaths are one in twenty four. The only means of arresting these 

 misfortunes thus indicated by the ravages of death, is to endeavor 

 to enable those who gain their livelihood by the sweat of their brow, 

 to do it more efficaciously. Their labors must be rendered more intel- 

 ligent, easy and appropriate to their destination, and thereby suscepti- 

 ble of being better paid and more abundant. — Rev. Ency. Sept. 1829.

1 . JVotice of a new method of charring wood, in a letter to the Ed- 

 itor, from Mr. Isaac Doolittle. 



My Dear Sir — My occupations for the last seven years, have led 

 to pretty extensive and close observations on the manner in which 

 charcoal is made in our woods and mountains ; and which I always 

 considered as an exceedingly laborious, wasteful and slovenly opera- 

 tion — but one which I knew not how to improve upon, until about a 

 year since, when my attention was called to examine a small charring 

 kiln at the works of the West Point Foundry Association. This 

 kiln was made on the same principle, and nearly of the same size as 

 one described by M. de la Chabeaussiere, (Bulletin de la Societe 

 d'Encouragement pour I'Industrie Nationale, Vol. XX. p. 295.) 

 This was a pit dug in the ground, filled with wood, and covered with
