The revenues of the municipality are so small in comparison with what they should be that it is a difficult matter to find any excuse for the theory of government that existed in the days when perpetual franchises were given away. It is small consolation that the policy of municipal ownership is at last to prevail after so much of the public property has passed into the possession of private corporations. If all the outstanding franchises that were the property of the people had been sold on short terms for percentages even as large as have been fixed in recent cases, the city to-day would drive from that source an annual revenue of more than $5,000,000, instead of the paltry $300,000 now collected. The mistakes of the past, however, are beyond undoing, and the taxpayers must look to the future for relief from the burdens they bear. They are paying now $15,000,000 a year for the sentiment that demanded a city great in all save honesty and political wisdom. Consolidation in fact as well as sentiment must result to prove the material advantage of the arrangement. Public opinion and politicians must realize sooner or later that income and expenses are to be adjusted the one to the other upon sound and enduring principles of business, honesty, and intelligence. There must be a union of public and political interests. Every section of the great city must be brought into close touch with every other section by cheap and rapid transit. The possibilities of the future are greater than the dreams of to-day, but new policies and new methods must and will prevail. The development of Greater New York must not be hampered by a financial system antiquated and imperfect. The city should have power to develop its material resources into revenue-yielding improvements, and then, with honest and intelligent government, the burden of taxation will be reduced to a minimum, and the ideal of the grandest municipality in the world will have been achieved. A BUBBLE-BLOWING INSECT. BY PROF. E. S. MORSE. Many years ago, while preparing an elementary book on zoölogy, I had occasion to make a drawing of the little insect which is found on grass and other plants immersed in flecks of froth. This substance is commonly known as frog spittle or cuckoo spit, and, being found in the spring, is known in France as “spring froth.”
