This new district, to which all classes are now turning their attention, posseses a mild and genial climate, and a fertile soil awaits the labor of the agriculturist. All our upper Pacific coast has a range of temperature something like the west of England, though somewhat hotter in summer. The gold excitement will turn the world's attention to this land as a field of emigration, and will do much for developing the resources of what may prove to be one of the richest portions of the continent. FRDIT AND VEGETABLES.—At the present time New York market is well supplied with apples, peaches, plums, blackberries, watermelons, tomatoes, and green corn. Consequent upon the abundance of all these luxuries, the usual mortality among children prevails, otherwise our city is healthy. PONDERODS MACHINERY TO GO ABROAD.— The Novelty Iron Works have finished a lathe, to fill the order of a foreign government. Its weight is over 140,000 pounds, or about sixty tons. GRAY HAIR.—Some English writer has recently asserted that an undue proportion of lime in the system is the cause of premature gray hair, and advises to avoid hard water, either for drinking pure, or when converted into tea, coffee, or soup, because hard water is always strongly impregnated with lime. You may soften water by boiling it. Lot it become cold, and then use it as a beverage. VALUABLE PAPER MONEY.—Judging from the following notice of a Minnesota Bank, the money in that State must be below par : " It may be proper to add, that a bushel of notes are traded for an iron spoon at the place issued, and gradually lose their value while traveling to remote sections of the country." THE AMERICAN INSTITUTE FAIR will be held at the Crystal Palace, as usual, this year, and will commence on the 15th of September next. The managers arc making every exertion and sparing no expense to make the coming fair as fine an exhibitio I of American skill and invention as we have ever had in this country. Inventors from the country who wish to compete for the prizes had better begin making their preparations at once. LIGHT.—The celebrated savant Niewentyl, is said to have undertaken to count the num-bpr of particles of light that escape from a burning candle. By his computation, there are thus evolved at every second of time, " ten millions of millions times more than the number of grains of sand computed to be contained in the whole earth." If any mathematician can make a more nice and accurate calculation, it will be best for him to begin pretty soon. AN EXCELLENT WHITEWASH for ceilings of walls can be made of Paris white, 33 pounds, costing $1, and Cooper's white glue, 1 pound, costing 50 cents. Put the glue to soak in cold water over night; in the morning slowly heat until dissolved in the water. Stir Paris white into a small quantity of hot water. Then mix both, and add hot water to reduce to a proper milky consistency, and apply with a brush. It is probably better to keep the liquid warm over a fire, or by the occasional addition of hot water. A single coat of this is described as being equal to a double coat of lime whitewash, while it is far more brilliant and pure, and will not rub off. THE EFFECTS OF TOBACCO.—The Dublin Medical Press asserts that the pupils of the Polytechnic School in Paris have recently furnished some curious statistics bearing on tobacco. Dividing the young gentlemen of that college into two groups—the smokers and non-smokers—it shows that the smokers have proved themselves in the various competitive examinations far inferior to the others. Not only in the examinations on entering the school are the smokers in a lower rank, but in the various ordeals that they have to pass through in a year the average rank of the smokers had constantly fallen, and not inconsiderably, while the men who did not smoke enjoyed a cerebral atmosphere of the clearest kind. A NEW SLEEPING CAR.—The Great Western Railroad of Canada are engaged in building an experimental sleeping car, to combine the two desideratums necessary to insure comfort in day and night travel. We have not heard the nature of the plan upon which this car is constructed. But in coanection with this fact we may mention that since the publication of our article on the subject of sleeping cars we have had fifty different plans of seats, designed to embrace the objects desired, presented for inspection, and have applied and secured patents for a large number of them. We shall in a few weeks present to our readers an engraving and full description of Woodruff's patent seat and couch car, in j the form in which it is now being constructed for many of the western railroad companies,
