"There seems no danger of the speedy extinction of the species, as it is now known in quite a number of localities; and, contrary to the popular notion, there are immense numbers of younger trees of all sizes, from the seedling up to the largest. There has been much nonsense and error published regarding them."

Photographing the Interior of the Great Pyramid.—Our readers may remember that some time last winter a distinguished English savant, Professor Piazzi Smyth, went out to Egypt for the purpose of taking photographic views of the interior chambers of the great pyramid. The impossibility of lighting these vast halls had hitherto proved an insuperable bar to the undertaking; ordinary methods of illumination seemed, if we may so speak, to make no impression upon the thick darkness. But with the discovery of the wonderful powers of the magnesium wire light, this difficulty was removed. Professor Smyth writes as follows to the London Chemical News; his letter is dated East Tomb, Great Pyramid, February 2d:

"We are settled down at last to the measuring; the chief part of the time hitherto (about three weeks) having been occupied in concert with a party of laborers, furnished by the Egyptian government, in clearing away rubbish from important parts of the interior, [{282}] and in cleansing and preparing it for nice observation. The magnesium wire light is something astounding in its power of illuminating difficult places. With any number of wax candles which we have yet taken into either the king's chamber or the grand gallery, the impression left on the mind is merely seeing the candles and whatever is very close to them, so that you have small idea whether you are in a palace or a cottage; but burn a triple strand of magnesium wire, and in a moment you see the whole apartment and appreciate the grandeur of its size and the beauty of its proportions. This effect, so admirably complete, too, as it is, and perfect in its way, probably results from the extraordinary intensity of the light, apart from its useful photographic property; for side by side with the magnesium light the wax candle flame looked not much brighter than the red granite of the walls of the room. …Whatever can be reached by hand is chipped, and hammered, and fractured to a frightful degree; and this maltreatment by modern men, combined with the natural wear and tear of some of the softer stones under so huge a pressure as they are exposed to, and for so long duration, has made the measuring of what is excessively tedious and difficult, and the concluding what was, in some cases, rather ambiguous."

ART.

Domestic.—The National Academy exhibition will probably be open before our readers receive these pages; and from those cognizant of the internal arrangements of the new building, and of the preparations making by our resident artists, we learn that the collection will exceed in the number, and probably in the merit of the pictures, any of its predecessors. The make-shift character and unsuitableness of the rooms in which the Academy has of late years held its annual exhibitions, have deterred many of its most prominent members from sending in contributions, which they were satisfied could not be seen to advantage; and this sin of omission was so evident in the last two or three exhibitions, that one of the leading objects of the Academy—the improvement of public taste by the display of the annual productions of our best artists—seemed in danger of being defeated. The new galleries, it is said, can exhibit to advantage more than fifteen hundred pictures, and a capacity so ample, in conjunction with the prestige attending the opening of the new building, ought to cover the walls to their fullest extent. The public will not be surprised then to learn that an unusual number of artists have been, and are still, busily applying the final touches to their works, in anticipation of "opening day" (to borrow a phrase from the milliners); and it is to be hoped that the Academy, having now "ample room and verge enough" to satisfy fastidious members, may soon become the fostering abode of art which its projectors intended to make it. A slight foretaste of what the exhibition is likely to contain was afforded at the recent reception of the Brooklyn Art Association, where an elaborate and effective work by Grignoux, entitled "Among the Alps," and several by Leutze, Gifford, Huntington, Stone, White, Hart, Beard, and others, were on view. A number of pictures destined for the Academy were also exhibited at the monthly social gatherings of the Century and Athenaeum clubs of this city in the beginning of April. We propose to give an extended notice of the new building and its art collections in our next number.

The inaugural ceremonies of the New York association for "The Advancement of Science and Art" took place at the Cooper Institute on the evening of March 31st. One of the objects of the association is the collection and preservation of works of art, and one of the fifteen sections into which it is divided is devoted to the fine arts. Amid the multiplicity of special branches, which the association proposes to investigate and promote, from jurisprudence and the prevention of pauperism down to chronology, the fine arts must necessarily receive but a limited share of attention; but even this, if guided by taste and intelligence, is better than the indifference to aesthetic matters which is too often characteristic of a commercial metropolis; and the association will find plenty of well-wishers, and, we trust, some who will add substantial aid to their sympathy.

Among the attractions of the Central Park will be a hall of statuary, now in the course of preparation in the old [{283}] arsenal building near the Fifth Avenue, which is not yet open to public inspection. It will contain, what ought to prove a boon to all students of form, a collection of casts from Crawford's principal works. The Park Commissioners have, in this instance, shown an enlightened enterprise which might be imitated by wealthy private individuals. A few bronze statues of American statesmen, soldiers, or authors, placed on appropriate sites in the park, would add greatly to its attractions. And if it should be thought desirable to illustrate a national era, what one more worthy than the memorable epoch through which we are now passing, the termination of which will be coeval with the completion of the park?

A new group by Rogers, entitled "The Home Guard—Midnight on the Border," attracts throngs of gazers before the windows of Williams and Stevens's art emporium in Broadway. The story is naturally and effectively told. A mother and her daughter, the only inmates, probably, of some lonely farm-house, have been aroused from their slumbers by marauding bushwhackers, and tremblingly prepare to repel the assailants, or sell their lives dearly. The elder of the two females, with her body slightly poised on one foot, stands in attitude of rapt attention, while mechanically cocking a revolver, her sole weapon of defence. The daughter, less resolute in expression and action, cowers at her side. As a work of art, it is perhaps inferior to the "Wounded Scout" or "One Shot More," which exhibit the artist's highest efforts in characteristic expression and the management of details; but it presents a vivid idea of a scene we fear only too frequently enacted along the border, and will speak to aftertimes of the horrors of civil war. The steady improvement which Mr. Rogers has shown in his groups, illustrating the episodes of our great struggle, can be readily seen by an inspection of his collected works, the earliest of which were scarcely better than clever caricatures; and it is not surprising to learn that there is a demand for them in Europe, whither the artist himself proposes going during the present season. Foreign critics may now obtain a correct notion of the outward aspects of the participators in the war, if they cannot appreciate its motives or character. Mr. Rogers is at present engaged upon a group entitled "The Bushwhacker," which he will finish before his departure. According to one of the daily newspapers it "represents a wife in the act of drawing away from her husband—an old, grizzled, and care-worn fighter—his gun, and at the same time appealing to him to leave his perilous vocation. The Bushwhacker clasps in his arms his little child, who is toying with his shaggy beard. If we may judge from the half-relenting expression of his countenance, we can safely conclude that the wife will not sue in vain, although he still resistingly grasps his musket with one hand. The pose and execution of the figures are carefully attended to, and the work is one of the most spirited and successful of Mr. Rogers' productions."

Among other American artists who intend to visit Europe the present season, are Ives, the sculptor, and Haseltine and Dix, painters of coast and marine scenery. The last named gentleman four years ago forsook his profession, in which he had begun to attain some skill, to accept a place on the military staff of his father, Major General Dix, and now, with renewed ardor, resumes his pencil. He will study principally along the Mediterranean coasts.

A very miscellaneous collection of pictures, containing a vast deal of rubbish, and a few good specimens of foreign artists, was disposed of at auction by Messrs. Leeds & Miner, in the latter part of March, at tolerably fair prices. The following will serve as examples: "Snow Scene" by Gignoux, $900 (quite as much as it was worth); "Lady with Flowers," by Plassan, $750; "A Reverie," by Chavet, $850; "Evening Prayer," by E. Frère, $1,000; "The Alchemyst," by Webb, $380. A curious essay of Col. Trumbull in the perilous regions of "high art," entitled "The Knighting of De Wilton," fetched the moderate sum of $150. As an example of the style of composition and treatment affected by the painters who illustrated Boydell's Shakespeare Gallery, it was both amusing and instructive. Fortunately for his reputation, the painter of "Bunker Hill" and the "Sortie from Gibraltar" did not often recur to Walter Scott for subjects.
