We have in our possession a photograph likeness of the Moon, painted by herself in the reflecting telescope at Cambridge, Mass. The artist was Mr. Whipple of Boston, whose fame is co-extensive with our country. He has lately made great improvements in taking lunar photograph pictures, by daguerreoty-ping them on glass prepared for that purpose. Alex. Humboldt has written a letter, in which he advocates the construction of an oceanic canal, without locks, across the Isthmus of Darien, having reference to points on the Gulf of San Miguel, and Cupica. Next week the "Scientific American" will be illustrated with a large interior and ground-Dlan view of the Crystal Palace.

GRAIN WINNOWERS—By Geo. B. Salmon, of El-mira, N. Y. Ante-dat"d July 6,1853 : I do notclaim the blast head or the blast spout separately ; neither do I claim the screen nor the trough and spouts separately. But I claim, first, the expansion of the upper part of the blast spout, into the circular irregular enlarged head with an opening or mouth at the lower ex-tremity. partly covered with the sieve, for the purpose of allowing the force of the blast to be exhausted, the screenings immediately falling through the opening or mouth of the head while the blaat and dust escape through the screen, the blast being governed by a slide, as set forth. Second, Iclaim the arrangement and construction of the graduated sieve of unequal fineness, the portion being protected from the action of the fan blast, so that the small substances, such as cockle. &c, passing through and falling on the bottom board of the sieve, passing off at thetrough and spouts, and when the grain arrives at the coarser part of the sieve, it passes through and is acted upon by the fan blast, while larger substances than wheat pass over the end of the sieve, and fall on the floor, as set forth. [We maybe mistaken; but the first claim reads as if it were a similar improvement to that of Benj. D.

I also claim the method of heading spikes by bending the end of the rod preparatory to upsetting before placing it in contact with the heading dies, instead of giving it tho preparatory bending while in contact with the dies, whereby the heated rod is kept a shorter time in contact with the dies, and therefore heat them less, while at the same time it is not detained longer than usual out of the dies, so thatby this method the dies are better pro tected trora excessive heating, the rod from cooling, and the whole operation expedited and improved.as set forth.
