To the Members of the Institute: I have the honor to submit, on behalf of the Council, the following report on the affairs of the Institute from September 1, 1899, to August 31, 1900. As was hoped on the adoption of the new Constitution three years ago, the membership of the Council has continued fairly permanent. Only one change has been made in its elected membership. The Detroit and Connecticut Societies have so increased their membership that each is entitled to an additional member. At its last meeting the Council formally accepted a new affiliated society which had been formed in Missouri, and hopes for it a most vigorous growth. The membership of the Institute is now larger than ever before, numbering more than nine hundred. Since October of 1899, one hundred and forty members have been added, of whom nearly half are of the Detroit Society. The Financial Statement of the Treasurer shows a balance in favor of the Institute at the close of the fiscal year, August 31, 1900, of $1874.89. The principal part of this sum is already pledged toward the expenses of publishing the results of the excavations of the Argive Heraeum. For detailed accounts of the work and development of the Schools at Athens and in Rome, and of the excavations conducted at Corinth by the School at Athens, the reader is referred
