Gas lights.—The number of gas lights already in use in the metropolis of London amounts to upwards of 51,000. The total length of mains in the streets through which the gas is conveyed from the gas light manufactories into the houses now measure 288 miles.
Seed Potatoes.—It has been recently ascertained from the most decisive experiments, that late potatoes, or such as are not ripe, were the best seed, and that planting such restores a degenerated variety to its original qualities. The discoverer of this fact recommends the planting of seed from cold and late situations, and to plant so late as June and July, taking up those unripe, and preserving them as seed for the following year.

London.—The consumption of sheep and lambs in London, during the last twelve months, amounted in number to one million, sixty-two thousand, seven hundred. The number of horned cattle slaughtered, was one hundred and sixty-four thousand—and by the inspector's return, it appears, that the number of horse hides produced at Leadenhall market, amounted to twelve thousand nine hundred.
Boring legalized.—Last week we mentioned that a silver mine was said to have been discovered near Zanesville, in Ohio. By the last Columbus papers we are informed that the bill incorporating the "Muskingum Silver Mining Company" has passed the legislature.
It is said that the rock about twenty feet below the surface of the earth, extends under nearly the whole territory of Ohio; that the silver was found after penetrating the rock about 100 feet; and that, therefore, there is an even chance that this stratum of silver, near 7 feet in thickness, is as extensive as the state.
Verily, should this prove to be the case, what an alteration would it make in our affairs! Neighbouring states would supply Ohio with corn and whiskey—her keen speculators would become lazy nabobs—Yankee pedlars might venture to drive their trade there, without danger of being bitten—her rag banks, notwithstanding all that has been said to the contrary, would prove to have had at all times, a specie foundation: and Owl Creek and Cincinnati bank notes command a premium over eastern funds.
Capt. Symmes has long expressed great anxiety to get into the earth, and, as it is a long journey to the north pole, (where there is certainly a hole big enough for Capt. Symmes to get in) and the Captain says he cannot undertake the journey for the want of "disposable means,"—now, therefore, this may be entirely a manœvre of the captain's, or of his friends, to get a cheap passage into the earth, whereby he may embark near home, and without expense in the outfit. At any rate, we hope the company will persevere in boring—it is a good subject—for should they either find silver or provide a passage for Capt. Symmes, they will silence the hungry complaints of many speculators—both in real estate and in the learned and fashionable ologies of the day.
