Mississippian people in eastern Arkansas were using mounds when Spanish explorers arrived in 1541, and the Caddo in the Red River valley were still using mounds during the winter of 1691â92, when explorers from Mexico visited them.
The Linnie is about 16 cm (6.5 in) in length and has a weight of about 42 to 52 grams. It is mostly green and has black stripes (or bars) over its upper-parts except on the top of the head. Its lower-parts are olive-green with very dark green stripes on its sides.
This is also called wide duck and the weights (numbering system) are on the inverse scale. The weight of the fabric can be determined by subtracting the duck number from 19. A number 8 cotton duck canvas will weigh (19-8)= 11 oz per lineal yard of 22â³ width fabric. To get the ounce per square yard, you have to prorate it to 36â³ width since 1 square yard is 36â³x36â³. 11 oz per lineal yard(22â³) is the same as 18 oz/sq. yd.
