where there is a carrying place for half a mile, it is evident that this iron 

 may be advantageously wrought, not only for the supply of our territory, 

 but also for the inhabitants upon the St. John, for at Woodstock no less 

 than $120 is paid for a ton of bar iron, and we can afford to supply them 

 for a less price, with better iron than England can produce. This ore 

 yields fifty-three per cent, of pure metal, and will give sixty per cent, of 

 pig iron. It is the very best kind of ore to smelt, being easily mined, 

 and just heavy enough to make a good charge for the blast furnace. 

 Wrought by means of charcoal, it will yield iron equal in quality to the 

 best from Sweden, and capable of being wrought into the finest kind of 

 cast steel." 



The following is Dr. Jackson's analysis of this ore.

Much statistical information in relation to the limestone, gran- 

 ite, and other quarries, and the agricultural capabilities of some 

 parts of the State, as yet but little known, are set forth in the 

 economical and agricultural departments of the survey : the prin- 

 ciples on which are founded the application of science to farm- 

 ing, are also stated with great clearness, and several analyses of 

 soils from different parts of the State given ; but we have room, 

 under this head, for one extract only, which points out, we think, 

 the best plan yet offered for rendering agricultural and analytical 

 chemistry a thing practically attainable by our farmers. 



" Attempts have been made to render the art of chemical analysis 

 easy, so that farmers might be able to do them for themselves, but such 

 attempts have been entirely abortive, for it would presuppose a knowledge 

 of chemical science and manipulation rarely if ever in possession of any 

 but professed chemists, and it would be idle to put instruments and re- 

 agents into the hands of those who do not know how to use them. It 

 would certainly be very useful to the community, if our agricultural 

 brethren would establish a college or institute, devoted exclusively to those 

 arts appertaining to agriculture, and such institutions will ere long be 

 founded in each of the States, for we begin to see and feel the impor- 

 tance of a good scientific education among the farmers throughout our
