Note I-11 — Chapter I · ITINERARY: ST. LOUIS TO ST. PAUL, AUGUST 9TH-SEPTEMBER 21ST, 1805.

From Hamburg to Clarksville is 14½ m., Louisiana or Louisianaville, 24½; Pike went about 20, say to Krider's bend, and his camp was on an island which we may take to be that now called Krider's, 6 m. above Clarksville, 4 m. below Louisiana. The "continuation of islands" is now the following in ascending series, omitting about a dozen small ones; Mosier's or Mozier's, and Howard's, together, the former 1¾ m. long; Tilden's; McCoy's or Cock; Slim and Grimes, the former 3¼ m. long; Coon, 1 m.; Carroll's or Carle's, 1¾; Amaranth, small; Eagle, 1 m.; Clarksville, 2 m., opposite the town; Pharr's, 1¾ m.; and Krider's, 1 m. Above Mosier's isl. and ldg., on the E., is the outlet of Hamburg bay, 3½ m. above the town; Bay cr. falls into it. Behind Slim isl. is the chute of that name, into which falls the large creek called Guin's, Guinn's, Gwin's, etc.; and at the head of the island is the mouth of Ramsey's cr., another large one. These streams are both in Pike Co., Mo.; and as soon as Pike passes opposite Clarksville he has Pike Co., Ill., on his right, so that he sails many miles with a county of his own on each side. Clarksville, Mo., is something of a town, on the edge of the river, under the hill around which Calumet cr. comes to fall in just above; and 3 m. higher comes Little Calumet cr. on the same side. Opposite Clarksville is the lower opening of that immense slough whose character is not less remarkable than its name. This runs for more than 30 m. alongside the river, clear through Pike Co., Ill., and into Adams Co., forming a maze of channels which intersect one another and thus cut off various islands, besides opening into the Mississippi at several places; some of these lesser sloughs are called Spring Lake, Atlas, Cocklebur, Swift, Coon, Mud, Five Points, Crooked, Running, and Swan. This collateral water-course also receives a series of creeks, among which are those called Big or Big Stew, Six Mile, Honey or Hadley, Ashton or Fall, and Harkness. This whole affair is commonly called the Snicarty or Sny Carte; it is Suycartee Slough on Owen's map, and has other variants too numerous to recount. All these words or phrases are perversions of F. Chenal Écarté, lit. cut-off channel. For this and the corresponding formation of the name Sniabar or Snibar, given to a creek and town in Missouri, see my note, N. Y. Nation, Jan. 19th, 1893, and Lewis and Clark, ed. 1893, p. 29. The embankment built to defend the river from the slough is known as the Sny levee.
