NOTES—ORIGINAL AND SELECTED. 127 the track that an invader might be supposed to follow, so that while an army could not possibly live unless it took its own complete commissariat, the tribesmen would be in a position to fight to a finish."—From an article on Morocco in The Evening Standard and St. James' Gazette, 15th November, 1907. Subterranean Store-houses among the American Indians.—In Catlin's North American Indians (Letter 17) the author, describing a Mandan Village on the Upper Missouri, notes that the Mandans were in the habit of preserving corn in "caches." He says :— "They raise a very small sort of corn, the ears of which are not longer than a man's thumb. This variety is well adapted to their climate, as it ripens sooner than other varieties, which would not mature in so cold a latitude. The green corn season is one of great festivity with them, and one of much importance. The greater part of their crop is eaten during these festivals, and the remainder is gathered and dried on the cob before it has ripened, and packed away in 'caches' (as the French call them), holes dug in the ground, some six or seven feet deep, the [insides of which are somewhat in the form of a jug, and tightly closed at the top. The corn, and even dried meat and pemican, are placed in these caches, being packed tight around the sides, with prairie grass, and effectually preserved through the severest winters. "Corn and dried meat are generally laid in in the fall, in sufficient quantities to support them through the winter. These are the principal articles of food during that ong and inclement season ; and in addition to them they oftentimes have in store great quantities of dried squashes and dried 'pommes blanches,' a kind of turnip which grows in great quantities in these regions, and of which I have before spoken. These are dried in great quantities, and pounded into a sort of meal and cooked with the dried meat and corn. Great quantities also of wild fruit of different kinds are dried and laid away in store for the winter seas on such as buffalo berries, service berries, strawberries, and wild plums." Catlin's letter is not dated, but his travels among the Indians took place in "the thirties" of the last century.—T.V.H. The Mineral Springs of Essex: Additional Note.— Mr. Miller Christy and Miss Thresh in their lengthy article on this subject (E.N., xv., pp. 185-253) state (op. cit., p. 213) that they know nothing as to the exact site of the mineral spring reputed to exist in the parish of Markshall, near this town. I believe that I am able to indicate the spring in question, which is, without doubt, that situated in the meadow known as "Ladle Meadow," between Markshall Rectory and Tilkey, Coggeshall. Here, at the corner of a boggy grove, which is called "The Well Plantation" on the six-inch Ordnance Survey Map, there is still to be seen a stone basin, with a chain attached to it, which was formerly connected with a drinking
