A project has also recently taken form to establish a line
between Quebec and the Hudson Bay Company's posts north of the Columbia
River. With the two extremes so near meeting, a submarine wire would
soon be laid over Behring's Straits, or crossing at a more southern
point and touching the Aleutian Islands in its passage.
Two of the chapters of this work will be recognized by readers of the
"Atlantic" as having first appeared in its pages,--a chapter upon the
Progress and Present Condition of the Electric Telegraph in the various
countries of the world, and a description of the Electrical Influence
of the Aurora Borealis upon the Working of the Telegraph. These, with
a curiously interesting chapter upon the Various Applications of the
Telegraph, and an amusing miscellaneous chapter showing that the
Telegraph has a literature of its own, complete the chief popular
elements of the volume. The remainder is devoted mainly to a technical
treatise on the proper method of constructing telegraphic lines,
perfecting insulation, etc. In an Appendix we have a more careful
consideration of Galvanism, and a more detailed examination of the
qualities and capacities of the various batteries.
As is becoming in any, and especially in an American, treatise upon this
great subject, Mr.
