Chicago Notes.

<* One of the marvels of the recent electrical exposition at Frankfurt was a six-foot electric search lamp of 20,000 candle power. Schuckertt, the Nuremberg electrician, astonished Europe in its construction". Schuckertt is now at work on a larger light for the World's Fair. It will be seven and onehalf feefc, and of at least 25.000 candle power. The Frankfurt light could be seen plainly at Bingen on the Rhine, 45 miles away. It is expected that the search light at the World's Fair can be seen at least sixty miles away. Electrical Engineer Sasgent is making plans for a tower 300 feet high, on which the big light will be mounted. At a height of 100 feet above the ground will be two sixfoot search lights, and the three will suffice to illuminate the skies for miles around Jackson Park. Brilliant feats are accomplishtd with these search lights. Sheets of light can be projected with parallel, converging or diverging rays. When the rays are thrown out parallel a clearly defined sheet of flames seems to be suspended in the darkness. By changing the reflector the rays are brought to a focus at long di 3 tance from the central station. Those lights, turned on the buildings and alternately shot into the heavens or out across the lake, will producs brilliant electrical effects. The lofty stone monolith, which Wisconsin will exhibit at the Fair, will remain at Jackson Park permanently, the park commissioners having given their consent. The monolith is 107 feet high and cut from a solid block of stone.. The contract for its erection has already been let. It is probable that old Fort Dearborn will be reproduced in the Exposition grounds. Fort Darbort was a picturesque structure of tho block house description built by the Government in 1803, as a garrison for troops and for their protection against hostile Indians. Its first commander was Captain John Whistler, grandfather of Whistler the celebrated artist, now resident of London. Mrs Mary Shattuck, an alternate member of the Board of Lady Managers, is in charge of the efforts to reproduce the fort in Jackson Park Commissioners, who control the park, favour the idea and have consented to let the fort remain in the park after the Exposition closes.
