GEOLOGICAL SURVEY.
Work in the Grand Canyon to
 Be Stopped Shortly.

of the Grand Canyon, and the field parties of the U. s. Geological Sur vey which havo been engaged on it off and on for the last two years, will in a few weeks be withdrawn and transferred to another part of the territory. MT. F. E. Matthes, the topographer in chargeof the map work will spend the balance of the winter in the office at Washington preparing the maps for theengraves.
 They will be published in the form of two atlas sheets, which should be available to the public next summer. They may be se- cured upon application to the Di- rector of the U. s. Geological Sur vey for the sum of five cents each.
 The area covered amounts to 500 square miles, 300 of which lie be- tween the two rims of the Canyon.
 The section mapped extends from an east and west line four miles north of the mouth of the Little Colorado and cutting across the neck of Greenland, the great penin- sula opposite the Grand View ho- tel, as far south as Moran's Point and an east and west line across the Coconino plateau four miles south of the Bright Angel hotel. Westward it extends as far as Point Sublime on the north rim) and the head of Long creek lon the south -rim;) and eastward it ex- tends to the west boundary of the Navajo Indian reservation. It takes in three miles of the canyon of the Little Colorado and a con- sidera ble strip of land south of the same, including Gold H:ll, Cedar Mountain, and part of the lower Coconino Basin. Deer Tank falls just outside the south east corner. The Grand View Hotel and Hance's ranch are about a mile south of the south edge. The heads of Bright Angel canyon and of the double canyon of Cristal Fall creek lie en- tirely within the boundaries of this map.
 Particular pains have been taken to locate all known springs, tanks and other water supplies. All trails which can be travelled by pack an- imals are shown in dotted, black lines, while wagon roads are shown by solid double lines. The contour lines there is one at every 50 feet altitude-are published in brown; and, owing to their great density, form the bulk of the mapwork.
 The general tone of the map will be light brown, while all water will be shown in blue, so that it may be easily distinguished. The eleva- tions of all pinnacles and buttes in the Canyon will be put on the map, along with the name of these features. Besides these, the loca- tions of all benchmark tablets and posts will be shown together with the altitude stamped on them. There are a great number of these benchmarks scattered along the rim and down the principal trails as far as the river.
 As may easily be conceived, the surveying and mapping of such an intricately sculptured region as the Grand Canyon over an area of 800 square miles required considerable travelling, both by wagon and by packtrain. The mapping parties have had to cross the Canyon sev- eral times, usually via Bright An gel Canyon. In order to facilitate swimming the pack mules across the river at the mouth of Bright Angel Canyon, a sectional steel rowboat was purchased by the Sur vey and packed down to the river in two sections. It proved an un- qualified success, being strong, light and easily handled, even in a stiff current Besides, it possesses the great advantage over wooden craft in that # may be left on the sand
