* * * * * THE MAIN STAYS OF SCIENCE. The _savans_ at Hull have lately been giving some very interesting results of the trial of the strength of "stays." Surely this department should have been left to a female committee, for the true strength of "stays" can only be ascertained by experiments in very tight lacing. * * * * * A NEW TIDE OF EMIGRATION. Gold has been discovered in Scotland. This discovery may work perhaps a miracle. It may have the effect of sending all the Scotchmen, who for years have left their native country, "bock again." * * * * * ANOTHER "HEIGHT OF IMPUDENCE."--Naming a Railway Engine "Safety." * * * * * BRITISH ENTERPRISE. [Illustration: A] An opulent Bill-sticker has, we understand, made offers to the leader of the Chinese insurgent forces to rent of him, in the event of his being made Emperor, the renowned wall of China. The sum offered has not transpired, but it is said to be something extremely munificent. It is the billsticker's intention, as soon as he obtains an imperial grant, to form a company of persons who spend large sums of money every year in advertisements, and to cover the entire length of the wall with their bills and posters, a larger price being, of course, charged for those which will be posted inside than for those outside the wall, where comparatively but few people will be able to see them. The bills will be in English, or specially translated into Chinese, at the option of the advertisers. In the event of China being thrown open to English commerce--and there is, at present, every opening of such a fact--it will be at once seen what "a desirable medium for advertisements" this national posting-station will be. So favourably is the scheme entertained by some of our leading advertisers, that already have 12,000 miles of that part of the wall, which runs through the most densely populated districts of the Empire, been bespoken at an enormous rental. The company will be announced in a few days, and it is expected that the shares will be quoted on the 'Change at a heavy premium the very first day. MR. BERNAL OSBORN has been heard to say, "that next to a celebrated Marquis's property, it will be the largest hoarding in the world," and there is no doubt it will be. All our puffing tailors, pill-merchants, quack medicine-sellers, and Cambridge Sherry dealers, are actively on the look-out. Professor Liebig's testimonial in favour of Bitter Beer is already printed in all the Chinese dialects, only waiting to be pasted up. We shall keep our eye upon the wall. * * * * * DEAR ENTERTAINMENT FOR DEAR CREATURES. "MY DEAR PUNCH,
