This paper is a review of the two main lines of investigation which preceded the over-all attack of the problem of coal sampling by L. A. Bushell in 1937. The paper shows that the “simple” experiment fails to disclose the true nature of the problem. Use of the techniques introduced by R. A. Fisher et al. permits the evaluation of the sampling constants of a coal, and thus the formulation of a satisfactory sampling procedure. Certain simplifications of these techniques will permit the accumulation of variance data without undue expense. The methods of Visman, Tanner and Lerner, and those currently in use in Britain are compared with the direct analysis of variance.
