are no causes now existing in the waters, at least, which he has specified, 

 to prevent the propagation and increase of the salmon to any given extent, 

 if properly introduced, adequately protected, and suffered to visit its spawn- 

 ing places without interruption. 



That the object aimed at is worthy of a trial, is not to be denied or 

 doubted, and tbat, if attainable, it would be productive of great national 

 benefit, is as certain — it being no less than the creation, or, at least, the 

 regeneration, of a new, or quasi new, branch of national industry, which 

 would necessarily employ and produce a large capital ; which would give 

 work and wages to several thousands, probably, of hands ; and, what is of 

 yet more consequence, would furnish — in these times of high prices, scarcity 

 of provisions, and increasing demand for food — a cheap and abundant article 

 of nutriment for the masses. 



Again, the necessary outlay for restoring these waters is rated at so mere 

 a trifle, that it is unworthy of a thought — the estimated expense of stocking 

 the rivers named, in the first instance, not exceeding a thousand or two of 

 dollars, added to the individual outlay of a few mill-owners, in remodelling 

 their dams in a manner which would permit of the ingress and egress of 

 the fish, without in anywise affecting the height of the head of water, or 

 the supply maintained by the present system.

ILLUSTRATIONS OF INDUSTRIAL ART AND OBJECT-LESSONS. 



Oste of the prominent features of the day is certainly the increased 

 attention which is given by Government and individuals to the popular 

 illustration and exemplification of Economic Industry, and the application of 

 Science and Art to Manufactures. Lecturers, schoolmasters, and popular 

 writers all address themselves to this task, and with a very beneficial result ; 

 for the noble museums open for examination, and the subsidiary aid avail- 

 able, now serve to open up a vast field of interesting information to the 

 many, which was formerly confined to a few, and was scarcely considered 

 of sufficient interest to occupy the attention of the public. It is quite 

 useless to attempt to teach Natural History or the useful arts by books alone. 

 The lecture which is illustrated by diagrams, experiments, and specimens, 

 is usually far more popular than the mere viva voce explanation can be ; 

 and whether the study be mineralogy, conchology, or botany, a collection 

 of specimens is invaluable, both to the teacher and student. The illustra- 

 tion of commercial products, and their uses in the arts and manufactures, 

 by a well arranged compact cabinet of specimens, has not hitherto been 

 nruch attended to. Indeed, the task of collecting, systematically arranging, 

 labelling, and describing a varied assortment of specimens from the three 

 kingdoms, is no easy matter. This has, however, been well done within
