"Che Conservative. 9 olovatiou whore the Recreation League hns established one of its well-patronized gymnasiums. Undoubtedly , Clinton Park will serve to improve the condition of its immediate environment ; but it is altogether too limited in area to exert a favorable influence upon the district as a whole. A far greater improvement is now possible , in view of the fact that the growing necessity of building piers along the entire North Uiver front will in turn lead to the construction of a broad marginal avenue from the Battery to Fifty-ninth Street. Evidences of such an nvenuo are already visible at Christopher Street and at various points along the Battery. What a splendid opportunity for small parks would be here afforded ! From Manhattan Mar ket , at the foot of Thirty-fourth Street , to the terminus , a strip of land might be reserved except at street crossings wide enough for a continuous line of small parks similar in size to those extending - tending along Park Avenue. The only requisite here would be proper soil , banked sufficiently high to admit of the planting of numerous trees. If owners of large tracts of real estate , now remaining unimproved , were to assist in making such a betterment along the river , they would soon be repaid by finding lucrative employment for their property. Since the Back Bay of Boston was redeemed , the district has been transformed from a morass into the proudest quarter of the American Athens. Within three years from the time that work was actually begun (1877) ( ) , the surrounding estates had risen 50 per cent in value ; and this transformation mation has now spread far beyond Brookline. Similar improvements in New York would be attended by equally beneficial results ; and instead of being ashamed of the gates to our city , as we now must be , we should become proud of them. Wherever passengers descend from boat or bridge they should bo wel comed on our shores by a strip of greens- ' ' ' ward. As the tourist approaches harbors of the Mediterranean lying in the same latitude as our own , his eye everywhere beholds busy quays fringed with fresh verdure ; when he ascends the North River , he gazes upon a succession of nuisances all the way from the Ounard dock to Seventy-second Street. The contemplated extension of Riverside Drive Park to Spuyteu Duyvil has been estimated to cost $30,000,000 , and will when finished , benefit for some time to come a very limited number of people a small expenditure for the modest ex tension of Riverside Drive to the south would at once benefit a great portion ol the population , and perhaps clear the entire shore of crime. The value of trees as agents of sani tation has ever been recognized. Here' need refer only to the example of the Romans , who reared olive trees to absorb the malarial effluvia of the Cam mgua. Nor has this fact been over- ooked now ; for in many cities of the world , rows of trees have been planted n the streets to serve as arteries for the circulation of purified air. Unfortu nately , New York is a glaring exception to the rule , although no city ever pre sented finer opportunites for the culti vation of arboreta. When Henry Hudson discovered Manhattan Island , he found it covered with a primeval forest , traces of which may still be seen on Washing ton Heights and along the Boulevard Lafayette. In the days when the city barely extended beyond Fourteenth Street , and when our population was still comparatively poor , the trees sur rounding the dwellings of our citizens were objects of pride and solicitude. Today , the numerous stumps in the sidewalks of downtown streets bear silent witness to that ruthless process of extermination which has despoiled our city of its fairest ornaments. The conspicuous absence of trees from ; he residential streets of modern New York is hard to explain. Rich men who live here only during the winter appear to take very little interest in their fellow-citizens who are compelled to remain in town all summer. In some instances , indeed , the absence of trees in front of houses situated upon our park and river fronts seems to suggest a fear on the part of the owner that foliage might obscure architecture , apparently oblivious of the fact that the beauty of a dwelling is frequently enhanced thereby. As it is , few of our side-streets are embellished with vegetation ; and even along the Boulevard an avenue highly favored by nature the trees are neglected. This is true also of Seventh Avenue above Central Park , St. Nicholas Avenue , and of all other thoroughfares not placed under the jurisdiction of the Park Commissioners a body which should be authorized to exercise control over every avenue upon which the preservation of the trees is desirable. Except in front of St. Luke's Hospital , Morningside Drive , which is the glory of upper New York , is today barren of trees on its western side ; while on the historic King's Bridge road the few trees still remaining are sadly neglected What must we think of a corporation that recently spent the enormous sum of $7,000,000 on the construction of the Harlem Speedway , without exercising sufficient foresight to provide that fine avenue with a row of shade-trees for the protection of riders and drivers am their horses ? How different are the conditions in other American cities 1 Boston has its Commonwealth Avenue and other fine parkways which connect the old town with the suburbs. Buffalo boasts its Delaware Avenue , the ideal of an Amer ican boulevard , lined with comfortable homes , each surrounded by its garden The residential portion of Euclid Avenue n Cleveland is equally beautiful , and oven the founders of Chicago have hewn their appreciation of verdure. When I visited that city , Michigan Avenue was lined with cottages sur rounded by gardens , and presented a distinctively rural aspect. These cot- ages have now been superseded by ubstautial residences , hotels and club houses ; and the avenue , which , forty years ago , was hardly open beyond Twelfth Street , the present site of the Illinois Central Railroad Depot , has ) een extended for miles. Yet such is ts attractiveness today that it is every where referred to as a model of elegant municipal construction. Queens Borough , which undoubtedly s destined in time to become thickly populated , should be made as attractive as possible to prospective residents. No district of Greater New York presents iner opportunities for boulevards and : or the creation of paries and play grounds. Here , at last , we may relin quish that rectangular system which makes most American cities look so commonplace , and adopt , instead , diagonal crossings , with small parks and squares at every convenient point. The larger thoroughfares at present existing should be widened , and thus eventually become united with the central approach to the bridge. One of these , Jackson Avenue , leads from Thirty-fourth Street ferry to the charming village of Flush ing , where shade-trees in great variety have for several generations been cultivated citizens. Another vated by public-spirited other , Thomson Avenue , and its con tinuation the Hoffman Boulevard , leads to Jamaica , whose Forest Park , although nearer to the Battery than Grant's Tomb , is almost unknown. ' This sylvan retreat comprises 500 acres of virgin forest , traversed by secluded driveways and situated on hilly ground command ing a very extensive view of the sur rounding country. These are but a few examples of the excellent opportunites for municipal improvement afforded by the most ex tensive borough of Greater New York. The following table shows the annual total expenditure of four of the most important cities in the world , together with the amounts each of them has used for parks and parkways : Those who know the advantages of London and Paris over New York and Chicago , and compare the economical administration of those cities with our own , will appreciate that we have still some lessons to learn in municipal government.
