The future historians of this age will have to record no more mortifying illustration of the difficulties which in a republic prevent the success of great ideas than that which is presented in the case of Mr. Whitney, who early in the last month sailed for England. We transcribe with especial approval the following paragraphs respecting him and his labors, from the Tribune:

"If we are not mistaken, it is now nearly ten years since Mr. Whitney first devoted himself to his great project, and he has pursued it with a force of purpose, an intelligent apprehension of all its bearings and consequences upon the world, a nobility of ambition, and a sustained, intellectual enthusiasm which belongs to the rarest and most admirable characters. We do not know in any country a man in whom great intellectual and practical elements are more happily combined. It is not with the warm partiality of private friendship that we thus speak of Mr. Whitney, for, like all men of ideas, and all of nature positive and deep enough to have a special mission in the world, he puts others into relation with the thoughts which engage him rather than with his own personality, and you become intimate with them, not with him. A native, as we believe, of Connecticut, brought up to business in this city, where he acquired a competence, having conceived the idea of a vaster and more inspiring enterprise than the political and industrial world had ever attempted, he quitted the pursuits of trade, and the certain wealth they promised him, to perfect and realize his conception. He studied the great routes of the world, and the causes of their adoption. In a residence in Europe and by voyages in the East he made himself acquainted with the facts relating to the trade and productive capacities of Asia. He thoroughly surveyed and mastered the whole subject before beginning its discussion. Then he proposed the scheme to his countrymen, and for many years has sought exclusively to commend it to their favor. He has travelled in every direction, addressing public bodies and meetings of citizens, writing newspaper articles and pamphlets, and sparing no occasion to bring the idea and the facts connected with it to the knowledge of all. Wherever he has gone he has left some sparks of his own genial enthusiasm. The plan has found advocates in every section; many state legislatures have formally endorsed it, and a large party in Congress have been in its favor. Dependent altogether on his own pecuniary resources, Mr. Whitney, without compensation or assistance, has labored with a constancy and fidelity which could only proceed from a great purpose. But after this period of arduous exertion he has failed to carry his plan through Congress, while a great part of the lands on which he must depend for its execution, have already passed from the control of the federal Legislature. Accordingly, though he would greatly prefer that his own country should reap the splendid harvest of honor and substantial power which the building of this world's highway would assure, he has no choice but to consider the means which may be offered him for making it through British America. To the world at large the consequences would be the same, though to the United States very different.

"The route through British America is, in some respects, even preferable to that through our own territory. By the former, the distance from Europe to Asia is some thousand miles shorter than by the latter. Passing close to the northern shore of Lake Superior, traversing the watershed which divides the streams flowing toward the Arctic Sea from those which have their exit southward, and crossing the Rocky Mountains at an elevation some three thousand, feet less than at the South Pass, the road could here be constructed with comparative cheapness, and would open up a region abounding in valuable timber and other natural products, and admirably suited to the growth of grain and to grazing. Having its Atlantic seaport at Halifax, and its Pacific Depot near Vancouver's Island, it would inevitably draw to it the commerce of Europe, Asia, and the United States. Thus British America, from a mere colonial dependency, would assume a controlling rank in the world. To her other nations would be tributary, and in vain would the United States attempt to be her rival; for we could never dispute with her the possession of the Asiatic commerce, or the power which that confers."

But the matter reaches beyond the suggestions of national interest, and has a wider scope than the mere sentiment of patriotism. We have hoped that this republic might make the easy effort necessary to grasp a prize so magnificent, but we shall hail with satisfaction the actual commencement of such a work, wherever and by whomsoever it is undertaken.


A JEW AND A CHRISTIAN.

A few days ago, a man of various genius and acquirement, with whose writings people of many countries have been delighted, entered an office, holding in his hand two black-bordered notes, inviting him to funerals.

So—other friends have gone! who now?

Two persons very unlike each other. Truly I have never known more striking contrasts. I was meditating of popular prejudices by which their lives were more or less affected, by which their reputations were certainly much affected: one was a Jew, and the other a Christian.

Proceed with your morality.
