....Prospects for Mechanics and Laborers.

With respect to mechanical pursuits and trades, it will be obvious to the reader that the older States offer a wider scope for a greater variety of occupations than the new ones. But for all persons connected with muchanical pursuits, where utility is concerned, there is, generally, a certainty of employment and fair wages in most of the towns of any importance in Iowa. The following list will exhibit a pretty accurate statement of the average prices, (i.e.) journeyman's wages in the different towns. Of course, local and other incidental causes will frequently produce fluctuations in prices, and occasion variations from any fixed rule.
