Distance of slope stake from side or shoulder stake for any width roadway, slope 1 to i. It ground is nearly level the cut or fill at side stake is located by the double entry method in left column and top row. The number in body of table in same row and column gives distance from side stake to slope stake. It ground is not level estimate the difference in elevation between the side stake and slope stake, lower target by this amount if out, elevate if fill. Add this amount to cut or fill and find distance in table. Set up rod at this point, and line of sight should cut target if it does not make the slight adjustment necessary.

If ground is nearly level, the cut or fill at side stake is located by the double entry method in left column and top row. The number in body of table in same row and column gives distance from side stake to slope stake. If ground is not level estimate the difference in elevation between the side stake and slope stake, lower target by this amount if cut, elevate if fill. Add this amount to cut or fill and find distance in table. Set up rod at this point, and line of sight should cut target. If it does not make the slight adjustment necessary. TABLE No. VIII To find Tangent and External for curve of any other degree, divide by degree of curve and add correction found in column of corrections. Degree of curve with a given I may be found by dividing tangent, (or external). opposite I by given tangent, (or external). The distance from a point on the tangent to the curve is very nearly the square of the tangent length divided by twice the radius.

TABLE XIII--CORRECTIONS FOR TANGENTS AND EXTERNALS These corrections are to be added to the approximate values, found by dividing the tangent, or external,for a 10 curve (Table V III) by the degree of curve, in order to obtain the true tangents, or externals. Intermediate values may be obtained by interpolation. FOR TANGENTS ADD Daonas or Cunva

Professor Calvin R. Fremling State of Minnesota Winona State College Winona, Minnesota Dear Professor Fremling: Concerning your letter requesting information on the mayfly invasion aired Sunday, May 18. The mayfly invasion we spoke of occured July 12, 1954 and was run as a "nostalgia" piece on our Sunday news May 18. Some added information that you may be interested in is that the invasion occured during a period of some highly warm temperatures in downtown St. Paul. If I may be of any more assistance to you, please do not hesitate to contact me. Sine
y,
