[Specinl Comspondenoe.] New York, Sept. 17.- Last week the last of the summer girls returned to New York. This week they are buying f all gowns. I know what pretty gowns there are to choose from. One is of drab cheviot in shepherd check, the check being moss green. Tlie skirt is walking leugth (which mean8 that it just clears the ground), and has a nniple hem, and a few upturned plaits at tlie waist and fan plaits at the bak. There is a very handsome jacket basque of moss green faille, with bronze buttons. The vest opens over a white pique shirt front, with standing collar and white satin tie. The revers to the jacket are of drab faille the exact shade of the ground of the dress. The hat is of very fine drab feit, with a narrow bias border of the same material as the dress. The ribbons are bronze green and the feathers drab, shading to brown. The back of the basque is plain coat. Another elegant fall walking costume is of striped camel's hairinpalest biscuit color, the stripes being only due to shading produced by the weave. The skirt apparently opens in front over brown faille, and the side draperies (as well as the bottom, and, indeed, every edge) are bordered with a narrow, brown silk gimp. The basque is slashed and bordered like the skirt. The front has a simulated girdle of brown faille, studded with large nail heads. Above this is a full vest of biscuit colored faille (everything is faille now), and the revers are the same, studded with more nail heads. The bonnet to match this costume is of biscuit colored noil, trhnmed with brown velvet ribbons and velvet pansies with a little russet grass. The back of the basque is cut quite plain, with the seams left open for the slashes. In being thus careful to give all the details, I hope that those who see the pictures will have no difficulty in making a gariueut like either of these if they please. Any seasonable goods is adapted to these styles, and it requires about five yards of material forty-f our inches wide, aside from the trimming for each. Bicycling is now apparently a fixed fact for girls, and during the bracing autumn months there will be inuch opportunity, and so here is a new and modest bicycling costume, which is put forward by our best houses. The tight basque and ordinary skirts have not f ulfllled all the requirements. This costume has a blouse that is partly basque, yet allows the freest movement. The skirt is a plain ane, like any, but at the bottom there is a drawing string on each side for abont twenty-four inches, or more if desired, and when about to mount the strings are pulled in and tied around the ankle, just above the boot top. This gives it the appearance of Turkish trousers without the uncomproraising ugliness of the divided skirt. Enough of the skirt should be left between the two gathered places to allow free movement. It does not take a ute to untie the tapes and make tlia skirt into a nest walking dress again. This can be made of serge, cheviot cloth or flannel, and a vest of quilted eilk or chamois cati be worn under the blouse for extra cool days. It does not matter greatly what style of hat is worn, but the bicycle makes the lady rider appear rather conspicuovis, anyhow; 60 the cjuieterand more modest and unobtrusive lier costnme the better it is. Perhaps one of the soft woolen caps now worn so much would be the most suitable, but it should match the costume, and all should be of dark color. Gray is really the best color for bicycling, as the mud spots which are bound to pret on show less than on dark blue or black.
