The New Post-Office.—The foundation of this building is now being laid on the ground purchased some time ago from Messrs. Edwards and Co., and approved of by the Postmaster-General. The building, as we have formerly stated, is to be of Grecian architecture, and will front the sea. Its extreme length will be 53£ feet, by a little over 43 feet in breadth. It will contain five rooms on the ground floor and two small ones above. The sorting room, which will be lighted from the top, and will be of good height, about 18 feet, as it runs up to the roof without any intervening ceiling. There is the postmaster's room 14 by 10, the chief clerk's room of similar dimensions, a messenger's room of smaller size, and a fifth room still less, besides the two rooms upstairs. Round three sides will run a balcony, which will be in front 10 feet wide, and at each side 7 feet. The pillars of this balcony will look well, and indeed, judging from the plan, so will the whole building, though no doubt it will be overshadowed to some degree by tho large building now being erected for Messrs. Edwards and Co. It is a pity that the Government could not afford, funds to purchase the entire block, but it is no use regretting that now. There appears to be one improvement which we think might be made on the plan, and that is that the windows which seem too small should be considerably enlarged all round the edifice.

The Steamer Waxgaxut.—This vessel in appearance, mould, fittings, interior accommodations, engines and boiler, is as handsome and complete a steamer as is to be found in Australian waters, and well maintains the fame of the eminent Dundee builders, Messrs. Gourlay Brothers. The saloon of the Wanganui is roomy and tastefully fitted up with brilliant panels of stained glass and finely finished hand painting representing flowers and fruits. The couches are of crimson plush velvet, with ample sleeping room in the round stern and along the sides ; and altogether, with the bright and variegated stained glass of the skylight, it is a comfortable and cheerful room. She can carry 57 saloon passengers, including 8 for the ladies' cabin ; beeside3 22 in the fore-cabin. Her registered tonnage 13 164, and she can carry 200 tons dead weight. Her nominal engine power is 50 horses, which can of course be very largely increased, to fully 100 horses ; and she can steam 10 knots, fche has also an admirable adjunct, which no steamer should be without, in the shape of a steam winch, which occupies very little space and proves a cheap "lumper" of cargo. Tho Wanganui, which is commander! by Mr. Linklater, brought in her present trip 41 passengers from Wanganui, and left Nelson last night about midnight. We understand she is chartered for three trips from Wangauui to Raglan in Auckland province. One object of her visit to Nelson was to go on the gridiron to have her bottom cleaned, but the present tides not being sufficiently high, she will on an early occasion return here to have tho necessary operation performed.

No. 1 City Company N.R.Y.—A meeting of tho members of this corps took place on Wednesday evening last for tho purpose of nominating a captain in the place of Mr. N. Edwards, resigned. Captain and Adjutant Lockett ocenpied the chair, when Mr. Nathaniel George Morse was unanimously nominated. A resolution was passed to the effect that honorary members should bo admitted on payment of a yearly subscription of two guineas in advance. Five new members were sworn in. Mr. Edwards addressed a few remarks as to his resignation, giving with other reasons one to the effect that he could not, from business engagements, devote that time and attention which the interests of the Company required a person holding tho position of Captain to do. A voto of thanks was passed to Mr. Edwards and the Chairman, and the but>inesa terniintsted.
