The coal strike in the Ruhr is certainly awkward for you, but what gives? The ill-advised strike of angry passion is, as matters stand, the usual way that large new strata of workers are brought in our direction. These facts seem to me to have been given too little consideration in the treatment by Vorw rts. Liebknecht knows no shadings, he is either all black or all white; and if he thought he was duty-bound to prove to the world that our party did not egg on this strike, and even calmed it down, then God have mercy on the poor strikers for them less than a desirable amount of concern has been shown, to see that they come to us soon.
