Minnesota has but one mineral in such abundance as to be a great financial asset, but in that one—­iron—­it produces over half the output of the Lake Superior region, which alone of the United States iron fields produces any considerable quantity of ore of a quality required for manufacturing Bessemer steel.  The analysis of the ores and names of the mines were given on the samples, which were shown in nearly 100 large glass jars.  A chart of the Mesaba range; a large map of the State, showing the location of the mineral lands; two groups of photographic views of working mines and mining methods, in frames 3 by 10 feet in size, with statistical charts.  These constituted the wall display.  On the floor was a model, 11 feet square, of the Fayal, the greatest producing mine in the world.  This showed all the mining processes and every detail of shaft house, ore dumps, cars, tracks, steam shovels, telegraph lines, etc., in and about the mines.

The stone exhibit was also a practical one.  It showed the more marketable varieties as they appear in actual use.  There were five large wall pieces of granite, one of Winona stone, one of pipestone, and one of Frontenac stone.  Inclosing two sides of the floor space, which was 36 by 54 feet, was a low wall of stone, with two entrances.  The shorter wall was of polished granite from the St. Cloud quarries, showing all the more distinct varieties—­gray, mottled, black, red, and brown.  The wall on the longer side, beginning with a corner post and extending to the entrances, was of polished red granite, with a panel of Minnesota marble.  On either side of the side entrance, were high posts of Kettle River sandstone, handsomely carved, and the rest of the wall was of this stone combined in part with the Twin City brick.

An elaborate game and fish display was determined upon in the Game and Fisheries Building.  Every inducement was held out by the company, and an especial effort was made for this exhibit.  It pledged, among other things, that pure refrigerated water would be furnished for the fish.  The board consulted in this department the State game and fish chief, Mr. Samuel Fullerton, who extended all the assistance possible.  Eighty-four feet of aquaria were put in, and it is indisputable that they were the best built, most practical, and best arranged in the building.  At the close of the fair the Pacific Coast Association offered $1,000 in cash for them where they were, or nearly one-third of their cost.  They were planned to show not only the State’s trout and small fish, but the large game fish that are found there.  As it was, splendid specimens were shipped to St. Louis in the fish car of the Pennsylvania commission, loaned without charge for that purpose.  The fish arrived on Minnesota Day under the personal care of Mr. Fullerton and one of his wardens and of three Pennsylvanians, expert in such work.  The fish were in splendid condition, and they included wall-eyed
