The Mechanics’ Institute Pavilion. Wo give herewith « spirited illnstration of thenew Mechanics’ Institute Pavilion, now nearly completed on Union Square, as we expect it will appear on the day of its opening, when large crowds will be rushing thither for admission. THE EXTERIOR OF THE PAVILION. In viewing the Pavilion, as shown in the engraving, the observer is supposed to be standing at the corner of Stockton and Post streets. The strnctnre isa parallelogram in form, with its greatest length running east and west. Its entire length is 337 feet bya width of 205, exclusive of hoiler room, The number of sqnare feet of ground floor is 72,000, against 55,000, occupied by the pavilion of 1865-6. It is built entirely of wood, and the chief points aimed-at in its construction have heen lightness, strength and economy of cost and space, In securing these advantages, the architect, Mr. William Patton, has succeeded most admirably—snch is the universal verdict. The main hall of the bnilding is 272 feet jong and 180 feet wide, with a central, arched nave of the same length, 80 feet wide and 68 feet high, ocenpying the space beneath the elevated roof shown in the engraving. Around the entire nave rnns a gallery nine feet wide, with tweuty feet width at the end connections, which will he used mainly for promenade pnrposes. It will be reached by four wide stair-cases, two upon either side, and a steam hoistway willbe elegantly fitted up, near the entrance, after the style of the most approved hoist-ways in use at the hotels in the Atlantic States and Enrope. This, of itself, will form quite a feature in the exhibition—being the first of tho kind erected on this coast. The Pavilion will be lighted by continuous windows along both sides, while the front will consist of one semi-circular ‘window, of forty feet radins, arranged as shown by our artist. The whole will bo brilliantly illuminated in the evening by upwards of 1,200 gas burners. Tho main entrance is from Stockton street, and is flanked by two towers 80 feet high, surmounted by flagstaffs. The grand vestibule is 50 feet wide, and leads direct to the body of the building. The wing shown npon the right of the entrance is reserved for the exhibition of musical instruments, for which purpose its acoustic properties are very well adapted. This room will be 35 by 60 feet in area, and will be used as occassion may require for concerts. Adjoining this department on the left, and in the base of the right hand towerare the Committee Roonis. In cach of the towers, which are sixteen feet square, there will he four rooms. It was originally intended that the room on the left of the entrance, corresponding to the Music Room, should be occupied as arestaurant, with a ladies’ dining room and dressing room adjacent; but the calls from exhibitors for space is so much greater than was anticipated, that itisnow proposed ) VIEW OF THE MECHANICS’ to occupy this room also forexhibition purposes, and to erect an additional room on the south side of the main building for a restaurant, ete. THE ART GALLERY is placed across the rear of the main building, and is 205 feet long by 30 in width. It will receive an abundance of light from above, by a continuous line of perpendicu. lar sash, placed npou the roof, as shown in. the engraving, where the extreme northern end of the galleryisseen. Hasy and abundant access and egress to and from the Art Gallery will be obtained by fivo passageways—one from the nave, and two from each of the wings or aisles of the main hall. The walls of the gallery will bo tinted so ss to subdue the sharpness of the light, and relieve the paintings, photographs, cte., which will be placed upon the walls. This will form a most interesting feature of the exhihition, far exceeding anything of the kind hitherto witnessed on this coast. The varions artists of the city have largely enINSTITUTE FAIR PAVILION OF gaged space— so much so, that a portion, if not all the photograplis will have to he placed across one of the ends of the gallery . in the main building, which will be made of extra widtb, and eqnally well arranged and lighted for such purpose as the Art Gallery will he. : On the uorth side of the main bi] ding, . and near to the projecting wing, to be used as an exhihition room for musical instruments, two large rooms will be put up to contain the hoilersand engines which are to supply steam for the motive power to be used dnring the exhibition. eNE INTERIOR. It is designed to make the effect of the entrance something altogether superior to what has heretofore been attempted. As the visitor advances from the grand vestihule, he will behold an immense arched nave 272 feetin length, 80 in width and 68 feet high, flanked on either side by aisles of corresponding depth—30 fect in hight and 40 feet wide, and from which it will be separated by 2 double row of columns or rihs, upon which rest cighteen magnificent 1868. arches, each of eighty feet span,and supported upon piers, which spring up through the floor from the soiid earth below. These colnmns or ribs have been formed by bolting and clamping together eight planks, each two by six inches, §o firmly has this work heen done, that after the clamps which were used to hold the planks together were removed, the latter did not spring apart even one-eighth of an iuch. Around the hase of the arch are placed the spacions promenade galleries, already descrihed. The view from either end of these galleries, sweeping as it will throngh the entire main building, will he a most magnificent one. The area of the galleries will be about 3,000 superficial feet. In the center of the nave an elegaut fountaiu will Le erected, with an opeu space aroundit; while along the middle, east and west from the center, the horticultural display will be arranged. The working machinery will be placed upon the right of the entranceand within the northern aisle, The boilers and engine to drive the same, will be placed outside of the maiu uorthern wall, iu the open space seen in the engraving between the Music Hall! and the Art Gallery. In the sonth aisle avenues running from end to end of the building. CONSTRUCTION AND COST, The whole of the work of constrnetion has been done by day’s work, under the superintendence of the architect and the Cominittee, The building will cost, in all, abont $30,000. The qnantity of lumber used in its construction is about 600,000 feet, and 700,000 shingles huve also been expended in roofing. The wholeof the exterior work is now nearly finished. The interior will be completed by the first of August, when the Pavilion will be ready for the reception of goods. The goods and manufsctures to be exhibited will be divided into thirty classes, which are given in fnll on another page. Ovr Ocean Steam Mantye.—The ocean steamship marine belonging to this port, is rapidly increasing in importance. Six round trips are now made between this port and Panama every month. In addition to the New York connections at the Isthmus, these steamers also connect on the esst side with both English and French lines direct to Enrope; aud with Australian, Central and South American lines on the west side of the Isthmus. We have also a monthly line of steamers to Chinaand Japan; steamers making the round trip ,every twenty days to the Sandwich Islands ; the round trip as often, by another line, to Mexican ports ; a semi-monthly line to Britisn CoInmbia ; a tri-monthly to Oregon ; one coast line to ports in this State, to the north, and another to ports to the south of this city. The fleet required to accomplish this work unmber about forty steamers—nearly all first class and aggregating 60,000 of tonnage. Onr river fleet to various portions of the extensive Bay of San Francisco, upon the upper and lower Sacramento river, and on the San Joaquin, is also equal to the equipment for any similar trade in the interior waters of any country in the world, Tle sea-going sailing craft on its way to this port, ou the Ist inst., was 128 vessels, aggregating fnlly 100,000 tons, or neariy 800 tons each ; and yet the fearis that we shall be short of tonnage to take away our prodnetious for the enrrent year. It will require npwards of 300,000 of ssil tonnage to market our home products dnring the present season, exclusive of what will go by steamer. The total amonnt of tonnage which will enter and depart from this port during the coming year, will probably exceed 650,000 tons—over one-half of which will be hy steam. Gey. W.S.
