5. As the more fertile and accessible public lands in the Mississippi valley were gradually taken up, new settlers began to cast envious eyes upon Indian Territory, and especially upon a central region, called Oklahoma, or the "beautiful country," which was supposed to be very fertile. Several illegal attempts were made by bands of adventurers to settle upon these lands, and the military had been employed to eject the "Oklahoma Boomers," as the intruders were called. 6. The Indian title to Oklahoma had gradually been acquired by the United States, and one of the first acts of President Harrison was to issue a proclamation declaring that this region, embracing nearly 3000 square miles, should be thrown open to public settlement at noon of April 22, 1889. 7. As this date approached, settlers to the number of over ten thousand collected and formed camps along the southern boundary of Kansas, and, at the hour named, made a wild race to Oklahoma across the intervening strip of Indian Territory. Towns were started in several localities, and within a few days the region had a population of more than 30,000. Though the country proved somewhat less fertile than had been supposed, the new community continued to grow, and the following year, with greatly enlarged boundaries and a population of 62,000, was organized as the Territory of Oklahoma. [Sidenote: =Centennial of the Republic.=] 8. Within two months after Harrison's inauguration occurred the CENTENNIAL OF THE AMERICAN REPUBLIC. On the 30th of April, 1789, the Father of his Country had taken the oath of office and entered upon his duties as first President of the United States, and the corresponding date in 1889 was fixed upon for the centennial celebration of the event. The holidays in the metropolis included the 29th and 30th days of April and the 1st day of May. The event drew to New York the largest concourse of people ever seen at one place within the limits of the United States. Fully half a million strangers visited the city and were present at the ceremonies. [Sidenote: =The Samoan Difficulty.=] 9. The close of the year 1888 and the beginning of 1889 were marked by a dangerous complication between the United States and Germany relative to the Samoan Islands. In order to settle the difficulty, the President of the United States sent three commissioners to Berlin, to confer with the German Government. The result was wholly satisfactory to the United States. The attitude and demand of the American Government in favor of the independence of Samoa, under its native sovereign, were supported by the decision of the commissioners, and the difficulty ended with the recognition of King Malietoa.
