By the time we had been here about a month and had settled down a little, we set about clearing a tract of wild land called section 33, situated nearly twenty miles away. You will ask, What does section 33 mean? Oregon is divided into several districts. For the Willamette Valley the land-office is at Oregon City, one of the most ancient towns in the State, having a history of forty years, dating from the rule of the Hudson's Bay Company. The chief officer is called the "register." He is supplied with maps of the surveys from the central office at Washington. Each map is of one township, consisting of a square block of thirty-six sections of a square mile or six hundred and forty acres each. Each township is numbered with reference to a baseline and a meridian, fixed by the original survey of the State, thus giving a position of latitude and longitude. From the land-office duplicates of the maps for each county are furnished to the county-seat and are deposited in the county clerk's office for general inspection. Each year a certain sum is set aside for new surveys, and contracts are given by the Surveyor-General of the State to local surveyors for the work. The corners of each square-mile section are denoted by posts or large stones, and the neighboring trees are blazed or marked so as to direct attention to the corner post or stone. Thus for years after the surveying-party have passed through wild land, there is but little difficulty in finding the corner-posts, and thence by compass ascertaining the boundary-lines of any section or fraction of a section in question. Surveys being officially made, boundary disputes are avoided, or easily solved and set at rest by reference to the county surveyor, who for a few dollars' fee comes out and "runs the lines" afresh of any particular plot. Section 33, then, is the section thus numbered in township 10, south of range 7, west of the Willamette meridian. It lay just on the edge of the burned woods country. [Sidenote: _THE GREAT CONFLAGRATION._] Although forest-fires in Oregon are still of yearly occurrence, since settlement by the white men the range of the devastation has been by degrees narrowed and confined. Formerly the Indians started fires every year to burn the withered grass in the valleys and on the hillsides, and thence fire spread into the woods and ravaged many miles of timber. The "great fire" is said to have occurred about forty years ago, when many Indians perished in the flames, and others had to take refuge in the streams and rivers, till the destroying element had passed them in its resistless fury.
