Note 68 — [309] CHAPTER VI [XIII]

Just east of the ninety-ninth meridian, the Canadian almost touches the thirty-sixth parallel, and then turning southeast passes below the thirty-fifth, turning northeast again near the ninety-sixth meridian. The party is now near the bend to the southeast; the map probably shows them on the nineteenth too far along the southeast course. The stream flowing southeast was doubtless a tributary of the Washita. Gypsum (sulphate of lime) occurs in great abundance along the Canadian, especially between the ninety-ninth and one hundredth meridians. Near the ninety-ninth meridian begins a wooded district known as the Cross Timbers; it varies in width from five to thirty miles, and is four hundred miles in length, extending from the Arkansas to the Brazos.—Ed.
