A French company, of ample means, hav purchased a tract ofland at a short distanc east of the Crystal Lake, near New Eochelle where they have commenced the erection o a magnificent establishment for carrying 01 the manufacture of Bohemian Glass Ware.-The h Westchester News" states that th buildings will be of brick and stone, and pu up in the most substantial manner. Th principal building fronting the turnpike roac will be upward of 300 feet long, and four o five stories high; while in the rear there wi be several other buildings of smaller dimen sions, adapted to the wants of the variou branches of the business. One furnace alon will occupy a space of fifty feet square. The whole work is to be pushed most vigorously ; as soon as finished quite a colony of workmen aud their families are to be brought from France to carry on the business, which is expected to be very extensive. For the accommodation of the French families who are expected to be employed in the establishment, about fifty dwellings will be erected by the company. New streets are being laid out around the works. In the construction of vessels the process f calking the seams so as to exclude the wa-:er, forms an important part of the operation, 'his has heretofore been done by champering be outer edges of the planks, and then dri-ing oakum or other similar material between hem. An objection to this mode of calking s the well-known fact that the working and training of the vessel has a tendency to irow the oakum out, and render re-calking ecessary, while, at the same time, as the ilanks are not driven so close together, and onsequently car.not lorm a close joint; the mil will be less stiff anil rigid than is desira-le. The improvements represented in the an-exed engravings obviate these objections, nd consist in rendering the seams water-ight by placing between the edges of the ilanks some adhesive elastic substance or ma-erial, such as india rubber, gutta percha, or ompound of both. This may be lone by ach plank, and placing in the said groove a trip of india rubber, gutta percha or other lastic material, and then driving the planks closely together, the edges of the planks not jeing bevelled but square, so that they will form a clofe rigid joint. If desirable, it may ae coated with a rubber cement, or compound. Li the engravings, fig. 1 represents a side elevation of a portion of the hull of the boat, and figure 2 a transverse section, representing two methods of introducing the elastic calking above named, a different method being shown upon each side of the boat. I -i are the planks upon one side of the vessel, and a a those upon the opposite side ; c c are the joints which are calked by grooves, e, plowed in the edges of the plank, as shown, into which the long strip of elastic calking is introduced. This strip of calking may be round and tubular, or of any other required form, so as to fill the channel, which may also be of any shape desiredthe planks thus grooved or plowed are then driven together, with a coat of elastic cement between them if it is thought advisable. The calking intro duced between the planks, 6 6, as at/, is of different form from that at d ((; in this plac the planks are not grooved as in tne other instance, but are planed square, and a flat piec of the elastic calking doubled and placed be tween the edges, thus inlaying all the joint by the elastic material. The edges of thi calking may overlap the external corner o the plank, as shown in fig. 2 at/, and connected to the plank upon the outside, or the joint may be simply inlaid without the overlapping, as may be required. It will also be een that the ends of the planks and the seams of the upper works, or other parts of the vessel, may be calked in the same manner. By he above method of calking a vessel, it will >e seen that the necessity for chamfering the edges of the plank is entirely obviated, and >y cutting the edges square, and placing be-;ween them an adhesive elastic substance, the oint will be impervious to water, and at the ame time the hull remain extremely stiff nd firm, while the calking cannot be work-d out by the straining or working of the vessel, as frequently occurs in the method of calking haretofore practiced. Further in-brmation may be obtained by letters address-d to the inventor, B. F. Cooke, of Boston, Vlass. Mr. C. has taken the necessary mea-nres to secure a patent. By the latest news from Europe, it appears bat the celebrated city ot Nankin had been aptured by a powerful army of revolutionists who will, to all appearances, soon overthrow he present Dynasty.
