In fact, it may be argued that it is not wise to diverge from the methods now in vogue as they are the only ones which have been applied with any commercial success whatever. THE CENTRAL RENDERING STATION. The failures in the operation of centrally located rendering plants have been as numerous as and far more conspicuous than the successes. The causes operating to bring about these failures, it appears at this distance, were manyfold. Speaking of the failures collectively and not as individuals, it is evident that over capitalization and extravagance in expenditure for equipment, the failure of equipment to yield its expected performance, errors in the location of the plant, and general inexperience all contributed. The plan has inherent faults. These are twofold: The high expense involved in hauling the raw material to the plant and the lack of machinery which would make the rendering process continuous, automatic, and economical. A further disadvantage, applying to both proposed methods but in greater degree perhaps to that of the central plant, is the shortness of the season during which the plantwould be in operation. In this discussion the adoption of the plan is opposed further on the ground of its general failure to meet the demands of the problem. 1 For a brief discussion of menhaden oil see ibid., p. 46 et seq.
