Jack is aboard the “Spray” in the Sacramento River delta, “Somewhere between Bouldin & Antioch,” working during breaks in sailing. Charmian’s increasing role in assisting his writing career is evident, as is Jack’s continued involvement in the socialist movement. “Dear Mate – Expect to mail this in Antioch, if we make that berg to-day. Have just finished expanding the ‘Game’ to 15,000 words. Won’t bother with typewriting it, but shall send off the hand-written ms. by registered mail from Antioch. I don’t remember whether I told you, but the bookproofs should be sent off immediately. Ere this you should have received ‘Revolution,’ expressed you from Stockton. I replied to yours of Feb. 25th, from Stockton. Don’t Remember what I said except that I had to speak in Oakland, Sunday 12th. The socialists are in need of campaign money, are going to hire a theatre, & I’m going to give ‘Revolution.’ Don’t fail to express ‘Revolution’ to Jack London, Care Mr. E. Winship, Napa, Calif. and by the time you receive this letter, you can write me directly at above address. I don’t see my way to getting to Glen Ellen until after Sunday 12th. Let you know more fully later. You see, this Napa affair is a sort of a ‘Siberia’ re-union. Frazer arrives for it from England (on his way back to the war). Yes, Miss Mather will be there. I guess, if there’s a socialist local in Napa, I’ll give a lecture… Had a hot time Sunday night – never was so sharp, (brutal, I guess) in my life. I just flayed them alive. Gee! Even Cloudesley was impressed. Your own man.” It is not clear to what this last passage refers.
