The Chicago convention for the unification of the carpenters' trade all over the United States has had a most salutary effect already upon the social status and business prosperity of the profession. Within the last week wages have advanced almost universally 25 cents per diem, and at Burlington, Iowa, Aug. 3.— Carpenters' wages from $2 to $2.50 per day. No union. Work unsteady, but plenty of men best to do it. Will soon try to raise a club for The Carpenter. Yours truly, Geo. R. Lann No. 1, gent reading. It is well worth the subscription price of thirty cents per year. Among our labor exchanges deserving of particular mention are: The ‘Locomotive Firemen’s Magazine “Locomotive Engineers’ Monthly;” “Cigar Makers’ Journal” Indianapolis, August 25, 1881.— We received those papers and send you $1 in payment. I will write to you next Monday. The Carpenter is doing good here. We are always anxious to get it. We have just fairly started. We have been almost ashamed to tell our numbers, but we will have a union here after awhile that will stand. We are doing no shoddy work. There are not many carpenters yet that know what is going on. As soon as they get their eyes open, they will fall in line. There have been several unions started previously to this and have failed; Most makes it so much easier for us now.
