"It was in this office that he did what gave him a national standing, and led many people into the notion that some good had come from the Tammany Nazareth. The Chamberlain was custodian, under the old charter, of all city moneys. Such portions of these funds as were not required for immediate use, this official deposited in some of the banks, and the banks allowed interest, as is customary, on the weekly or monthly balance to his credit. Previous to Sweeny's time the Chamberlain had put this interest money into his own pocket--and a very handsome thing Mr. Devlin and his predecessors made out of the transaction. But Sweeny startled the political world, and caused a great sensation, by announcing that he should turn these interest receipts into the City Treasury. Tammany made a notable parade of his honesty and public spirit, and the capital he gained in this way has been his chief stock-in-trade for the last two or three years. "But in the light of recent developments, Mr. Sweeny's course does not seem so purely disinterested as it once did. He was in full control of the city funds on the memorable Black Friday of two years ago last summer, and sworn testimony taken by a committee of Congress shows that he had a share in the doings of that eventful day. To what extent the money in his official charge was put at the service of the Wall street Ring, the country probably never will know; but the common belief of New York is that Mr. Sweeny made a good deal of money out of his speculations on that occasion. That he has been more or less concerned with Fisk and Gould in various Erie Railway stock operations, is matter of general notoriety; as it is also that most of the lately-exposed fraudulent transactions in connection with the so-called new Court-House and other public buildings occurred during his incumbency of the Chamberlain's office. The greater part of those transactions yet brought into daylight refer to county affairs, it is true; but city and county are one except in name, and we have only just begun to get at what are designated the city accounts.
