We see, by a letter in the New York papers, that Elijah White, who went as United States agent to Oregon, and took with him a large party of emigrants, writes, under date of August 17th, that his party had increased to one hundred and twelve, although they had lost two, one by sickness and the other by accident. They started with nineteen wagons, and their journey had been slow and tedious; but they had passed two thirds of the way, and were in excellent health and good spirits. A favorable opportunity for emigration will occur in April, through the aid of Mr. Fitzpatrick, at Independence. Mr. White advises those who intend to go to prepare light strong wagons, and to take no loading except cooking utensils, and provisions for four months. Mules are preferable to horses. He says no doubt exists as to ultimate success of the colony." * * * * * From the _Jeffersonian Republican_, September 17, 1842. THE SETTLING OF OREGON. We learn with gratification that it is at least rumored that an expedition is about to be got up in Saint Louis, to colonize the rich and interesting Territory of Oregon. To such as have so laudable and advantageous an enterprise in view, we are prepared and feel warranted in saying, that it rests not upon "rumor" that many of our fellow-citizens of upper Missouri intend emigrating to that highly celebrated region next spring, and will no doubt be glad to be joined by as many of the enterprising citizens of Saint Louis as may think it their interests to join them. We learn from the "Oregon Correspondence Committee" of this place, that already they are beginning to receive names of gentlemen desirous of joining the expeditions, and from present indications, there seems to be no doubt remaining that there will be quite a large company formed. Let not those who now [have it?] in contemplation, draw back, but steadily persevere, and they may confidently promise themselves success. The country which they seek is no doubt one of equal attraction and advantages as any on the globe, and we rest assured that so soon as the number of inhabitants will justify, the fostering hand of a territorial government will be extended to it. Up then every pioneer, and let your cry be "Onward!"--_Western Missourian._ * * * * * From the _Ohio Statesman_, March 7, 1843. LETTER FROM AN OREGON EMIGRATION AGENT TO A FRIEND AT PITTSBURG.
