Show not hard to estimate contents of haystack estimating the amount of hay in a stack seems on the face of it to be largely a matter of guesswork but federal experts have worked out a method of figuring which his been found to come within 5 per cent of accuracy on all occasions the method is based on the shape of the as the deciding factor an overall measurement Is taken that is from the ground on one side over the top to the grou ground nd on the other side in the case 0 of a round top stack for instance forty six hun of the width is subtracted from fifty two hundredths of the overall measurement and arid this result Is multiplied by the width and length of the stack with the cubic foot capacity of the stack it Is then a simple matter to divide by the num ber of cubic feet per ton of the varl ous grains which go into the stack |
