Assuming, then, the advantages of a Zoological Garden in Philadelphia, what is necessary for success and what business inducements (to consider it in that light) can the society hold out to obtain sufficient money to procure its collection of living animals, and provide for their suitable accommodation and increase? The number of members is now two hundred, who pay five dollars initiation and the same amount annually, which gives them continual admission to the proposed Garden. Fifty dollars secures a life-membership free from any further subscription. The sum now in the treasury is two thousand dollars, and although at the last meeting twenty-one new names were proposed, and many more persons have announced their intention of joining, it is apparent that by this means the society will never accomplish its object. Begging subscriptions, without offering a pecuniary return therefor, is repugnant to the officers, and the following plan has been adopted for procuring the necessary funds. Certificates of stock are to be issued of not less than fifty dollars each. All receipts derived from the Gardens and collections of the society are to be applied annually--first, to the maintenance of the establishment; second, to the payment of six per cent. on the stock; and third, any balance remaining to go to the gradual extension of the collections of the society and the improvement of its grounds. It will be observed that stockholders can never receive a larger dividend than six per cent. per annum, and this only in case the receipts exceed the expenditures. There are therefore two points to be considered by those willing to invest--first, the character of the managers, and second, the prospect of the pecuniary success of the enterprise. The first is a matter of acquaintance and reputation: the second can be demonstrated in favor of the society, if honestly and efficiently managed, with almost mathematical accuracy. The main entrance to our Gardens will be directly opposite the Lansdowne drive, at the west end of Girard Avenue Bridge. The Park Commissioners' Report for 1872 gives the recorded number of pleasure carriages and sleighs entering the Park at this point and at the Green street gate, during the year, as 363,138, of equestrians 26,255, and of pedestrians 385,832. These, in the words of the report (p. 60), "allowing three persons for each vehicle, will make a total of one million five hundred and one thousand four hundred and ten visitors passing these two entrances; and supposing the number of persons coming by the other ten entrances to be not more than those recorded at these two, we shall have three millions as the approximate number of visitors."
