Each one of the foreign colonies entered heartily into the exposition spirit, and planned to present to the city some memorial in the way of a permanent work of art, in commemoration of this first centennial of the revolution which led to the independence of Argentina from Spanish rule or misrule, a date which is as sacred to the Argentinians as the Fourth of July with us. The British colony, which is one of the largest and wealthiest and numbers probably twenty-five thousand, presented a clock tower of artistic design. The German colony, of almost equal numbers, began the erection of a monumental fountain on a great and imposing terrace which was prepared by the city, and cost one hundred thousand dollars. The Austro-Hungarian collectivity offered a meteorological monument, similar to those found in the cities of Austria and Hungary, which will be adorned with meteorological implements and appliances. The Italians, who are the largest in number but not the wealthiest, built an artistic monument in Italian marble of that great discoverer, Christopher Columbus. Lastly, the three hundred Americans offered a statue of George Washington, to whose work and example more than anything else the liberty of all the Americas is due, and the government donated to them a beautiful location on one of the principal plazas. Thus, by this tribute, will another connecting link in the friendship between the two republics, each of which is predominant on its own continent, be added.

Plazas were rearranged, and new monuments erected in them; public buildings were redecorated and overhauled; the new Supreme Court Palace was hurried in order to have it ready for the sessions of the Pan-American Congress, which were held there contemporaneous with the exposition; six solid blocks were bought and condemned in order to give an approach to the new Congress Palace, and thousands of men were employed for months in tearing down these buildings, hauling away the débris, and preparing the ground for the beautiful little park into which the space has been created.
