"If the polling station officials represent a proper balance of political opinion, fraud will be difficult, and the fairness of the ballot should be judged by two main criteria alone: the number of electors who have cast votes compared with the number of ballot papers in the ballot box. The first measure can be determined by the number of signatures in the electoral register. Human nature being what it is (and quite apart from any intention to defraud), it is difficult to achieve total congruity between the two measures, and any further controls such as numbering the stubs of ballot papers or comparing the total number of ballot papers found in the ballot box plus those cancelled and unused with the number of ballot papers issued to the polling station may give some indication, but one should be under no illusion that the results of these various measures will coincide perfectly. The risk in multiplying the measures used is rather that the differences in the totals, and in the end the real irregularities, will not be taken seriously. It is better to have strict control over two measures than slack – and hence ineffective – control over a larger number of variables. "
