There are seven public schools, four of which are organized under the Union School system. There are six Churches—one Catholic, one Dutch Reformed, one Methodist, one German Methodist, one Congregationalist, and one Episcopal. There are one Lodge of Good Templars, one of Odd Fellows, and one of Masons. The City possesses a commodious Public Hall, erected in a substantial manner of Milwaukie brick, at an expense of over $12,000. It is divided into a Council Chamber, a Public Hall for meetings, lectures, concerts, &c., a room for market stalls, and a calaboose or jail. The warehouses, stores, hotels, and dwellings of the citizens, for solidity of structure and architecture, taste and adornment, are, as a whole, superior to most places of its size, east or west. There are of houses and places of business and industrial occupations as follows:

The central engine house of the Chicago and Rock Island Bail Road is located here. As the engines, with their engineers and firemen, are changed here, many of the employees are domesticated. The quantity of grain purchased direct from the producers, and shipped—exclusive of that purchased by the mill—was 582,641 bushels in 1857, against about 900,000 bushels in 1856. The falling off is attributable to the reluctance of the farmers to market their grain in the fall of the former year, as before mentioned.

A very important branch of business pursued here is the ice trade. About 13,000 tons are annually packed for the southern market, giving employment to about three hundred men, during the Winter and Spring in packing and shipping, and sixty men in Summer and Fall, in building boats and other preparations for the next winter's business. Two steamboats are owned and employed exclusively in the trade.

For some years, attention has been attracted to the Great Central Coal Field of Illinois, the north eastern rim of which underlies the cities of Peru and La Salle. From the earliest settlement of the country the outcrops have been resorted to for fuel. More and more extensive explorations and excavations have, from time to time, been made, excited by the foresight, sagacity and scientific deductions of the pioneer of that interest, Dixwell Lathrop, Esq. In 1855, a thorough examination was made by J. G. Norwood, State Geologist, which demonstrated the existence of three veins or strata, underlying an area of about 500 square miles. These veins vary in thickness, from three and a half to seven feet, the central being the thickest, but the value of the coal increasing with the descent. The existence of another strata, still lower and still better, is presumed, as the alluvial formation, or coal measures, has not yet been passed by boring. A comparison of the analysis of these coals with those of the best Pennsylvania and Ohio bituminous, demonstrated that an open market could be successfully entered in competition. Immediately afterwards, operations in mining were commenced on a more extensive scale and more scientific principles.

Several shafts were sunk and powerful and improved machinery employed. These shafts were sunk in and near La Salle, with one exception, which was in the westerly part of Peru, immediately on the river bank, and on the track of the Chicago and Rock Island Rail Road. The structures, excavations, machinery and outfits of the company operating this shaft are of the most perfect and approved kind. Their facilities for raising are equal to three hundred tons per day. They are working the lower, or best vein—four and a-half feet thick—exclusively, which they have reached at probably its greatest depression, three hundred and forty-six feet below the surface. Analysis and tests, made at many gas works and manufactories, are conclusive in establishing the fact, that no coal has yet been raised, west of Ohio and north of the Ohio river, which is equal to the coal from this shaft, for the amount of steam it will generate, and for its freedom from sulphur and tendency to clinker. What is true of this shaft is true, in a degree, of the coal from the same vein from the shafts at La Salle, the difference being due no doubt to its greater depression.
