Who blames them if they fall by the way? Even the sergeant of the division, passing their crumpled bodies by the roadside, becomes a hypocrite if he kicks them into an obedience of their orders. In his heart he might well wish to drop out as they have done. Who blames them, too, if they slink off, hiding behind any cover that will conceal their trembling bodies until the whole army has gone by?--who blames them if they sham illness, lameness, anything that may be put forward as an excuse to set them free?--who blames them if a wayside cottage offers them shelter and, taking it, they leave the other poor wretches to go on? Who blames them then? No one--no one with a heart could do so. The great tragedy lies in the fact that they are left to blame themselves. And this--this is the way that Nature wages war--a civil war, that is the worst, the most harrowing of all. She fights her own kith and kin; she gives battle to the very conditions which she herself has made. There is very seldom a hand-to-hand encounter. Only your French Revolutions and your Russian Massacres mark the spots where the two armies have met, where blood has flowed like wine from the broken goblets of some thousands of lives. But usually it is the forced marches, with the enemy ever retreating over its own ground. And in this position of women, it is the army of Nature that has begun to move. Not the mere rising of a rebellious faction, but the entire unconquerable force of humanity whose whole existence is threatened by the invading power of population. And Sally Bishop--frail, tender-hearted, sensitive Sally Bishop--has donned the bandolier and the haversack and is off with the rest, just one unit in the rank and file, one slender individual in Nature's army that is out on a campaign to effect the inevitable change in the social conditions of the sex. It makes no matter that she will never reap the benefit; it counts not at all that she will never touch the spoil. The lines must be filled up. When she falls, there must be others to take her place. The bugle has sounded in the hearts of thousands of women of her type, and they have had to obey its shrilling call. Stand for half an hour in the morning at any of the main termini of London's traffic-ways, and you will see them in their thousands. They little know the law they are obeying; they little realize the cause for which they are working, or the effect it will produce. In another book from this pen it has been declared that the words of Maeterlinck--"the spirit of the hive"--are an inspired phrase. Here, in these conditions, with no need to don the protecting gauze, you may see its vivid illustration, as only the great draughtsmanship of life can illustrate the wondrous schemes of Nature.
