numbers. The objectives underlying the present paper were (1) to derive, for the twoway classification, necessary and sufficient conditions which must be satisfied by the subclass numbers in order for linear functions of the variance components to be estimable and (2) to determine, for the same classification, those sets of subclass numbers for which two commonly-used variance-component estimation procedures, Methods 1 and 3 of Henderson [3], yield unbiased estimates of the components or linear functions of the components. Observations yijk are taken as having the linear model
