New Yobk, August 8, 1881. Editor Courier: A cool wave has reached licre at last. It is tliankfuüy received, and very few inquire whether its birth place was Manitoba or Labrador. Duriug the heated term, the thermometer at no time wentabovo 90, but the heat was terribly oppressive from the dampness of the atmosphere. The daily lista twenty or twenty-flve, prostrated by the ehafts from l'lm'ljus' bow no longer appear in the papers and the jingling of the ambulance bells is not so oontinuously heard as it was last Tbursday and Friday. On tliose days the buildings and pavements seemed to be fairly blistering In the sun'a rays. The hurrying crowds in Broadway and the Wall street región, for the most part left their vests at home and wore linen or alpaca coats, while many were to be seen with no coat at all, fanning themselves in a listless, desperate manner. There was a general transfer of capital by vendors of canes and 'patent garters, who do business on the Broadway sidewalks, from Uieir recular trade to the fan business, aml tlie capital was well invested, for the price of fans rose 50O per cent. It's an ill wind tbat blows nobody good, even if it comes from the torrid zone, at least that la what tlie soda fountain men and (Joney Island innkeepers think. The trade of the latter has languished this season and they were beginning to get discouraged, till the late heated term came to their aid. At no timo this sumraer have there been sucli crowds at Coney Island or llockaway Beach as there were all last season, aml even on Sundays or flrework nights, when tseenicilas though tliererould lic no more peopie ieft in New York, the crowd were only a litüe inore than half the regular size of last sunimer's throngs. A huge tavorn containing 018 rooms has just been openeü at Kockaway, and a good deal of interest is feit iu its success or f ai I n re, as it is general ly tho opinión that the fortunes of this hotel will in a mensure decide whether tbe building ot' mammotb seaside hotels has been overdone or not. 'I'here is no city in the world that is better provided than New York is witli sumuic r resorte, where a picasant day or evening may be speitf, or witli so many excursión routes, by which a beautiful water trip with sea, river or niountaiu scenery, may be taken. There are swift iron steamers running hourly from the Hattcry down the harbor, through the Narrows, out into old Ocean and to the iron pier at Coney Ialand. The round trip, with a fine concert in the pier pavillions at either end and music on the boats thrown in, costs 50 cents. Thefre are five trips mado by the Long Branch boats and the round trip costs 60 cents. Then there are steamers leaving hourly for Glen Island, a charming day resort thirty miles up the East River aud out into the Sound, with the fare around only 50 cents. There aredaily boats going up the Hudson, the noblest of streams, and Sundays a boat runs up to Newburgh and back, 120 miles, all for 50 cents also. These are a few only of tho dozens of opportunities, which the toiling thousands have for breathing the fresh air and for leaving the heat, the dust and the worry of city life behind for a few hours to get that reireshment for body and spirit, whicli nature alone can give. Thousands upon thousands go away from the city every evening by scores of routes aud many other thousands have Ieft the city for the smnmer. vet romo from aunriac to sunset as loud apparently as ever, and there are, to all appearances, as many people elbowing each other, and as much business done in the city as before. It is gelting to be very conimon now, more and more so every year, for eyery foreigner who has a pet scheme, for which be nceds money or sympathy, to take the flrst steamer for "the great, good and riek" America, thinking that there is no nation so gullable as the " great Yankee nation." Two of these foreigu boogare have just left us, Father QtTazzi, tlie Free Catholic priest of Italy, and Leo Hartman, the Russian asunta, while l'arnell is expected before long on another begging tour. Hartman canie for sympathy, but found that the available sympatliy of the country was all in use for the stricken President. He has lately gone to Cunada, or as some reports say to the frontier, so that he can be in either the United States or Canada on a moment's notice. whichever political atmogphere Menu more fully chargod with sympathy for assassins. He was not overwhelined willi the out pouriugof public sympathy ben in New York and fouml that hU brother in crime, Guiteau, had injured his prospocts slightly by turning that sympathy in another direction. It also became fcpparont tohimthat many peoplewhn hul thougktlesBly rejoloed at the murder of the Czar hadsincebecomeconvinoed that minder was murder. Several of the journab of the serai-dynamite stamp have been eomparing Hartman, poorsufferint; patriot that he Is, to Kossutli, and have been clalmlng that t would be as just to have givcn up "Kossuth for extradition as it would to send Hartman back to justice. This ploa is so logical and the comparison between Kossuth and Hartman is so exceedingly close that there is very serious talk. of calling poor Hartman back, giving him a public banquet and telling him how sorry New York is for him and for Guiteau. After -'Lord" Uoscoe's memorable vindication, the newspapers were without any stock subject for some time, until, luckily for them, the " Infernal machines" were ...! in titivipooi uu] IHIee tnen O' "Dynamite" Iiossa and Crowe of Peoría have been vieing with each other in empty vaporings about the aiiniliilation of the British merchent marine, all of whicli is a rich mine for the dailies at tliis dull season. The Tribune aptly remarked recently that, "if O'. D. Rossa would sit down real hard on adynamite machine and explode it, de would do a good stroke of business for Rossa, for Ireland, and for the United States." So say we all of us.
