The Congress having provided for "an appropriate national celebration of the Centennial Anniversary of the Establishment of the Seat of the Government in the District of Columbia," the committees authorized by it have prepared a programme for the 12th of December, 1900, which date has been selected as the anniversary day. Deep interest has been shown in the arrangements for the celebration by the members of the committees of the Senate and House of Representatives, the committee of Governors appointed by the President, and the committees appointed by the citizens and inhabitants of the District of Columbia generally. The programme, in addition to a reception and other exercises at the Executive Mansion, provides commemorative exercises to be held jointly by the Senate and House of Representatives in the Hall of the House of Representatives, and a reception in the evening at the Corcoran Gallery of Art in honor of the Governors of the States and Territories. In our great prosperity we must guard against the danger it invites of extravagance in Government expenditures and appropriations; and the chosen representatives of the people will, I doubt not, furnish an example in their legislation of that wise economy which in a season of plenty husbands for the future. In this era of great business activity and opportunity caution is not untimely. It will not abate, but strengthen, confidence. It will not retard, but promote, legitimate industrial and commercial expansion. Our growing power brings with it temptations and perils requiring constant vigilance to avoid. It must not be used to invite conflicts, nor for oppression, but for the more effective maintenance of those principles of equality and justice upon which our institutions and happiness depend. Let us keep always in mind that the foundation of our Government is liberty; its superstructure peace.
