What made the business more difficult still was the incredible shortage of skilled labour. Owing to our deplorable predilection in the army for putting square pegs into round holes, there were trained engineers sweeping out mess-huts or carrying stretchers; capable mechanics digging holes or grooming horses; and skilled draughtsmen addressing envelopes and writing: "Passed to you, please, for information and necessary action," on documents referring to the momentous question as to whether No. 54321 Dr. Jones, R.H.A., should have a pair of new breeches at the public expense or pay for them out of his beer-money. All were very necessary tasks, no doubt, but requiring the right men to do them; and the engineers very urgently wanted the right men, too, not merely for making the docks, but for their multifarious activities in the field. In their search for them they went through the army like a scourge. A trade-testing centre was established at Kantara to which from every unit in the field or at the base came butchers, bakers, miners, moulders, brass-founders, electrical, mechanical, and civil engineers, draughtsmen, men accustomed to all kinds of steel and iron work, and railwaymen. All were tested practically in their respective trades by an expert in that trade, after which they were graded according to their proficiency and knowledge, transferred to the engineers, and sent about their proper business. By this system the cream of the skilled trades was obtained; and there was the double satisfaction that the men were not only working at the jobs for which they were best suited, but were helping materially to win the war. The scheme went further. As the supply of really skilled men was necessarily somewhat small, and the need great, the apprentices and semi-qualified men were eliminated from other units by the same process of selection, sent to Kantara and given the opportunity of learning more of their trade, being tested from time to time to learn the measure of their progress, until they could take their places amongst the qualified men. Thus a constant supply was more or less assured, and the O.C. of a Field Company of Engineers requiring, say, a fitter or a wheelwright or a moulder, merely asked for them in much the same way as one orders a ton of coal; if the goods, so to speak, were to be had, he got them. So sedulously were the records of trades kept that the authorities never lost touch of the men, especially of those engaged in intricate or delicate trades. On one occasion a skilled instrument-maker journeyed 1200 miles to Kantara in order to do a job for which he happened to be the only man at the moment available! And similar cases might be multiplied almost indefinitely.
