It being desirable to ascertain the fitness of the river La Plata and its tributaries for navigation by steam, the United States steamer Water Witch was sent thither for that purpose in 1853. This enterprise was successfully carried on until February, 1855, when, whilst in the peaceful prosecution of her voyage up the Parana River, the steamer was fired upon by a Paraguayan fort. The fire was returned, but as the Water Witch was of small force and not designed for offensive operations, she retired from the conflict. The pretext upon which the attack was made was a decree of the President of Paraguay of October, 1854, prohibiting foreign vessels of war from navigating the rivers of that State. As Paraguay, however, was the owner of but one bank of the river of that name, the other belonging to Corientes, a State of the Argentine Confederation, the right of its Government to expect that such a decree would be obeyed can not be acknowledged. But the Water Witch was not, properly speaking, a vessel of war. She was a small steamer engaged in a scientific enterprise intended for the advantage of commercial states generally. Under these circumstances I am constrained to consider the attack upon her as unjustifiable and as calling for satisfaction from the Paraguayan Government. Citizens of the United States also who were established in business in Paraguay have had their property seized and taken from them, and have otherwise been treated by the authorities in an insulting and arbitrary manner, which requires redress. A demand for these purposes will be made in a firm but conciliatory spirit. This will the more probably be granted if the Executive shall have authority to use other means in the event of a refusal. This is accordingly recommended. It is unnecessary to state in detail the alarming condition of the Territory of Kansas at the time of my inauguration. The opposing parties then stood in hostile array against each other, and any accident might have relighted the flames of civil war. Besides, at this critical moment Kansas was left without a governor by the resignation of Governor Geary. On the 19th of February previous the Territorial legislature had passed a law providing for the election of delegates on the third Monday of June to a convention to meet on the first Monday of September for the purpose of framing a constitution preparatory to admission into the Union. This law was in the main fair and just, and it is to be regretted that all the qualified electors had not registered themselves and voted under its provisions. At the time of the election for delegates an extensive organization existed in the Territory whose avowed object it was, if need be, to put down the lawful government by force and to establish a government of their own under the so-called Topeka constitution. The persons attached to this revolutionary organization abstained from taking any part in the election.
