ELBRIDGE BOYDEN, Architect. Mr. BROWN: SIR,--I have examined your work on architecture, and feeling confident of its utility, from its extreme simplicity and singular adaptedness to meet the wants of the carpenters, I do cheerfully recommend it to the condition of every carpenter, especially the apprentice, who will find all the rudiments of architecture necessary, as well as designs for practice.
