The following letter, published in the San Francisco _Truth_ some time ago, will be read with interest. The letter is quoted as follows, in substance: “I am an officer in the army of the United States, and know whereof I write. John Upton said to me, with great earnestness, that the day of armies is passing away. I believe this. This introduces my subject. I desire to place the details of the science of butchery before the people; to point out its weak points, so that in future uprisings the people may stand some chance of winning. They have for the past twenty years been overcome only because of their own ignorance. They have been slaughtered and subdued because of a lack of coolness, want of knowledge, and adherence to what is called ‘humanity,’ ‘honorable warfare,’ etc. I assume that my readers agree with me that against tyrants all means are legitimate, and that in war that course is best, though bloodiest, which soonest ends the contest. My purpose is to persuade the people to add a little common sense in future to their heroism, and thus insure success.

This is a bit of doggerel directed against the capitalistic press, and in advocacy of the _Arbeiter-Zeitung_ and of Johann Most’s paper, _Die Freiheit_. 7. “Proletarians of all lands, unite.” 8. This is a bit of Socialist “poetry” expatiating on the efficacy of the “boycott.” BANNERS OF THE SOCIAL REVOLUTION—III. FROM PHOTOGRAPHS.]
