But, of course, the question of the permanence of the labor armies is not so important as the question of getting the skilled workers back to the factories. The comparative success or failure of soldiers or mobilized peasants in cutting wood is quite irrelevant to this recovery of the vanished workmen. And that recovery will take time, and will be entirely useless unless it is possible to feed these workers when they have been collected. There have already been several attempts, not wholly successful, to collect the straying workers of particular industries. Thus, after the freeing of the oil-wells from the Whites, there was a general mobilization of naphtha workers. Many of these had bolted on or after the arrival of Krasnov or Denikin and gone far into Central Russia, settling where they could. So months passed before the Red Army definitely pushed the area of civil war beyond the oil-wells, that many of these refugees had taken new root and were unwilling to return. I believe, that in spite of the mobilization, the oil-wells are still short of men. In the coal districts also, which have passed through similar experiences, the proportion of skilled to unskilled labor is very much smaller than it was before the war. There have also been two mobilizations of railway workers, and these, I think, may be partly responsible for the undoubted improvement noticeable during the year, although this is partly at least due to other things beside conscription. In the first place Trotsky carried with him into the Commissariat of Transport the same ferocious energy that he has shown in the Commissariat of War, together with the prestige that he had gained there. Further, he was well able in the councils of the Republic to defend the needs of his particular Commissariat against those of all others. He was, for example able to persuade the Communist Party to treat the transport crisis precisely as they had treated each crisis on the front-that is to say, to mobilize great numbers of professed Communists to meet it, giving them in this case the especial task of getting engines mended and, somehow or other, of keeping trains on the move.
