2d. Mr. John M. Earle, of Worcester, Mass., solicits contributions to his collection of fresh-water shells. "I have a higher object in view," he remarks, "than the mere making of a collection--viz., doing what I can to ascertain what new species remain undescribed, and what ones of those already described may be only varieties of others; and, in fine, by a careful examination of a large number of shells, brought together from various localities, to fix, more accurately than it has heretofore been done, the nomenclature of the several genera and species, and so particularly to define their specific characteristics as to leave little doubt on the subject. The great variety of our fresh-water shells, exceeding that of any other country, seems to require something of this kind, in addition to the valuable labors of Say, Barnes, Lea, and others, who, although they have done much, have yet left much to be done by others, and have made some mistakes which require rectifying."

14th. Mr. Trowbridge writes from Detroit: "The period intervening since your last visit to this place has been an eventful one to the nation. South Carolina, driven on by a few infatuated men, has made a bold effort to shake off the bonds of Union and Federal Law, and, to the minds of some in whom you and I repose the utmost confidence, a happy government seems to totter on the brink of dissolution. It is a long story, and the papers will tell you all. God grant that the impending evil may be averted, and that the moral and religious improvement of this government may not be retarded by civil war." It is thought that this event, and the course taken by the President, will produce a great reaction in his favor, and that he will be supported by his old political opponents. The governor is much occupied. It is supposed the proclamation is from his pen.

18th. M. Merrill announces the opening of an infant school, in which he is to be assisted by Mrs. Merrill, on Monday next.

21st. Rev. J. Porter, pastor of the Presbyterian Church, reports to the Algic Society, that there is but little in the present state of religion here that is propitious. "Of the little church gathered here during the last year, ten persons are absent, scattered wildly through our land. There now remain twenty-six or twenty-eight communicants. These seem, in a measure, discouraged by the present indifference. The recent apparent conversion of three or four soldiers, and the increasing interest in their prayer-meetings and Bible class, give us some promise. The Sabbath School, taught entirely by members of the church, is now in a state of pleasing prosperity. And the infant school, lately organized under the direction of an admirably qualified teacher, promises to gratify the hearts of parents."

22d. The geography of the line of country between Sault St. Marie and the shores of Lake Huron, opposite to the island of Mackinack, is a perfect terra incognita. It has been passed in the winter only on snow shoes. The distance in a direct line from N.E. to S.W. is about forty or forty-five miles. It is about double that distance by the St. Mary's River and Lake Huron--which is and has been the ordinary route, from the earliest French days, and for uncounted centuries before. Mr. G. Johnston, who has just passed it, with Indian guides on snow shoes, writes: "I reached this place at half-past twelve this day, after experiencing great fatigue, caused by a heavy fall of snow and the river rising. I inclose herein a rough sketched map of the region through which I passed, that is, from Lake Superior to Lake Huron in a direct southerly line.

"The banks of the Pe-ke-sa-we-see, which we ascended, are elevated and pretty uniform. From its mouth to the first fork, is a growth of cedar, on either bank, intermixed with hemlock, pine, birch, and a few scattered maples. Thence to the third fork, denoted on the map, the growth is exclusively pine and fir. This river is sluggish and deep, and is navigable for boats of ten to fifteen tons burden, without any obstruction to the third forks. Its width is uniform, about sixty to seventy feet wide.

"From this point to Pine River of Lake Huron, is invariably level, gently rising to a maple ridge, and susceptible of a road, to be cut with facility.

"The banks of Pine River are very high. The river we found open in many places, indicating rapids. It is obstructed in many places with drift wood. The pine ridge, on either bank, indicates a vigorous growth of the handsomest pine trees I ever beheld. The water marks are high--say ten to twelve feet, owing to the spring freshets.

"I reached the mouth of the river on the Sabbath, and encamped, which gave the Methodist Indian an opportunity of revealing God's Holy Word to Cacogish's band, consisting of thirty souls. We were very kindly received, and supplied with an abundance of food--hares, partridges, trout, pork, corn and flour. We had clean and new mats to sleep on."

Feb. 4th. The American Lyceum at New York invite me, by a letter from their Secretary, to prepare an essay on the subject of educating in the West.
