This paper deals with an empirical investigation of various stratified two-stage sampling systems for estimating totals of certain agricultural items of North Carolina. The 1940 Agricultural Census data were used for stratification, selection and estimation purposes. The observed data were the results of the 1945 Agricultural Census. Theory for the selection of n primary sampling units from a stratum with probability proportional to some measure of size but without replacement has already been developed by the senior author [11]. The principal contribution in this paper is the application of this theory to the selection of two primary sampling units without replacement from a stratum, where one of the units is selected with probability proportional to size and the other with equal probability. These results are compared with sampling systems (i) where both units are selected with probability proportional to size but with replacement and (ii) where an equal number of primary sampling units are selected but only one from each stratum.
