PROFESSOR JOHNSON, author of the well-known work on Agricultural Chemistry, has been delivering lectures upon the results of his recent tour in the British Provinces and the United States, in one of which he observed, “In New Brunswick, New England, Vermont, New Hampshire, Connecticut, and New York, the growth of wheat has almost ceased; and it is now gradually receding farther and farther westward.  Now, when I tell you this, you will see that it will not be very long before America is unable supply us with wheat in any large quantity.  If we could bring Indian corn into general use, we might get plenty of it; but I do not think that the United States need be any bug bear to you.”  Prof.  J. was in New York last March.

CHARLOTTE CUSHMAN, with Miss Hayes, the translator of George Sand’s best works, was at the last dates on a visit to the popular poetess of the milliner and chambermaid classes, Eliza Cook, who was very ill.  Miss Cushman is really quite as good a poet as Miss Cook, though by no means so fluent a versifier.  She will return to the United States in a few weeks to fulfill some professional engagements.

RICHARD S. MCCULLOCH, Professor of Natural Philosophy at Princeton College, and some time since melter and refiner of the United States Mint, has addressed a letter to the Secretary of the Treasury, in which he states that he has discovered a new, quick, and economical method of refining argentiferous and other gold bullion, whereby the work may be done in one-half the present time, and a large saving effected in interest upon the amount refined.

THE LATE SIR JOSEPH BANKS lies buried in Heston Church.  There is neither inscription, nor monument, nor memorial window to mark the place of his sepulture; even his hatchment has been removed from its place.  Surely, as President of the Royal Society, a member of so many foreign institutions, as well as a man who had traveled so much, he should have been thought worthy of some slight mark of respect.
