In the acquisition of certain representative species of great variety but particular desirability, the Society has been much favored by its friends, both at home and abroad. Frequently it happens that the greatest zoological rarities are obtainable only through the good will and tireless industry of friends who travel into the most remote and inaccessible regions of the earth. It is to such sources that we owe our musk-ox herd, walrus, mountain goat herd, spectacled bear and many other species. The Executive Committee makes grateful acknowledgment of the loyal and generous support it has constantly received from the Board of Managers, the members of the Zoological Society, and from the Government of the City of New York. Thanks to a judicious union of these forces, the development of the Zoological Park has gone forward rapidly and satisfactorily. Although the actual period of construction has been remarkably short for so vast an undertaking, everything constructed is of the most permanent character. It is only just to note the fact that while the Zoological Park is an institution of national interest and importance, and free to all the world, with the exception of a few gifts of animals it has been created and is maintained wholly by the citizens of the City of New York. The State has contributed nothing. The Executive Committee. JUNE 1, 1913. CONTENTS.
