_Dear Sir_: Wednesday evening has been set for forming the Chicago
Bricklayers' and Stonemasons' Union. Meeting will be held at the
Builders' and Traders' Exchange at 7:30 P. M. Your presence is
desired, with all the bricklayers and stonemasons in your employ,
and if your men have any friends who wish to join said Union, bring
them with you, for the purpose of taking your first step for
liberty.
