increased, so long as the department is satisfied that the work is not costing more than it would have cost if let by contract at ordinary fair paying prices.... Another great advantage of {109} co-operation is that it gives the Government complete control over its expenditure. Under the old plan, when large contracts were entered into, the expenditure thereunder was bound to go on, even though, through sudden depression or other unlooked-for shrinking of the revenue, the Government would gladly have avoided or postponed the outlay.... Not only has the Government complete control over the expenditure, but in the matter of the time within which works are to be completed the control is much superior to that possessed when the works are in the hands of a contractor. When once a given time is allowed to a contractor in which to complete a work, any request to finish it in less time would at once provoke a demand for extra payment; but under the co-operative system the Government reserves the right to increase the numbers employed in any party to any extent considered desirable, so that if any sudden emergency arises, or an unusually rapid development in any district takes place, it is quite easy to arrange for the maximum number possible of men being employed on the works in hand, with no more loss of time than is required to get the men together."[3] It was at first proposed that the men should work in gangs of about fifty, who should have an equal interest in the contract and make an equal division of the wages and profits; but experience showed that large gangs did not work together harmoniously {110} owing to differences, not only in the temperament of the men, but also in their abilities as workmen. The labourers solved this difficulty by forming themselves into small parties composed of men of about equal ability, with the result that, while some gangs earn higher wages than others, the weak are not excluded altogether from employment. The co-operative works have, on the whole, been successful; but it is clear, from the reports of the surveyors, that constant supervision is necessary, and that there is considerable dissatisfaction, among unskilled workmen, with the low rate of their earnings, and, generally, with the intermittent character of the employment. For the Government have decided, in order that work may be given to as many as possible and that settlement may be promoted, that no labourers shall be employed more than four days in the week. During the remainder of the time, if they have taken up land in the neighbourhood, they devote themselves to it; otherwise they are likely to be demoralised by enforced idleness. The Minister of Public Works attempted to prove that works had been carried out more economically under the co-operative system, but was unable to cite cases that were exactly analogous. He showed that the average number of employes had risen from 788 in 1891-2 to 2,336 in
