Show mv not hard to estimate contents of haystack estimating sti mating the amount of hay in a stack seems on the face of it to be largely a matter of guesswork gness work but federal experts have work worked d out a method of 0 figuring which has been found to come within 5 per cent of accuracy on all occasions the method Is based on the shape of the stock stack as the deciding factor an overall measurement la Is taken that Is from the ground on one slue side over the top to the grou ground nd on the other side in the case of a roundtop stack tor for instance forty six nun of the width Is subtracted from fifty two hundredths of the overall measurement and this result Is multiplied by the width and iong length th of the stack with the cubic foot capacity of the stack it Is then a simple matter to divide by the number of cubic feet per ton of the various grains which go into the stack |
