The Apache scouts kept records of the time of their absence on campaign. There were several methods in vogue, the best being that of colored beads which were strung on a string, six white ones to represent the days of the week, and one black, or other color, to stand for Sundays. This method gave rise to some confusion, because the Indians had been told that there were four weeks, or Sundays (“Domingos”), in each “Luna,” or moon, and yet they soon found that their own method of determining time by the appearance of the crescent moon was much the more satisfactory. Among the Zuñi I have seen little tally sticks with the marks for the days and months incised on the narrow edges, and among the Apache another method of indicating the flight of time by marking on a piece of paper along a horizontal line a number of circles or of straight lines across the horizontal datum line to represent the full days which had passed, a heavy straight line for each Sunday, and a small crescent for the beginning of each month. It is not necessary to discuss the obvious method of repeating strokes, dots, knots, human heads or forms, weapons, and totemic designs, to designate the number of persons or articles referred to in the pictographs where they appear. SECTION 9. ACCOUNTING. The Abnaki, in especial the Passamaquoddy division of the tribe in Maine, during late years have been engaged in civilized industries in which they have found it necessary to keep accounts. These are interesting as exhibiting the aboriginal use of ideographic devices which are only partially supplemented by the imitation of the symbols peculiar to European civilization. Several of these devices were procured by the present writer in 1888, and are illustrated and explained as follows: A deer hunter brings 3 deerskins, for which he is allowed $2 each, making $6; 30 pounds of venison, at 10 cents per pound, making $3. In payment thereof he purchases 3 pounds of powder, at 40 cents per pound; 5 pounds of pork, at 10 cents per pound; and 2 gallons of molasses, at 50 cents per gallon. The debit foots $3.30, according to the Indian account, but it seems on calculation to be 30 cents in excess, an overcharge, showing the advance in civilization of the Passamaquoddy trader.
