Miss Klumpke was born in San Francisco, but was taken to Europe by her mother, who wished her daughters to have the best of opportunities. While in Germany, an old professor who took great interest in her used to lend her a small telescope, and it was then that she first formed her ambition to be an astronomer. After accomplishing some brilliant work in mathematics, she applied to the Directors of the Paris Observatory for admittance as a colleague. They hesitated to establish a precedent by admitting a woman; but they could find no rule on the books against it, so they gave her charge of a small telescope. She immediately started to work on her essay, which had to be written from indepen

The Mississippi as a Mill-Stream

By W. E. Pringle

NEW era in the developing of water power for industrial purposes is dawning in the West. A syndicate of Eastern capitalists, the combined rating of the members

aggregating $300,000,000, proposes to build a dam across the Mississippi river at Keokuk, Iowa, which will be the second greatest waterway dam engineering feat in the world. The dam which is proposed for Keokuk will generate 211,500 horse-power, with which to operate the industrial wheels in many cities.

This mammoth dam will be of solid concrete, 35 feet wide on the bottom, and about 30 feet high. This will be the first dam ever built across the Mississippi, the plans for which have been drawn under the direction of Hugh L. Cooper, who directed the power installation at Niagara.

The power house will be a magnificent structure of pressed brick and steel, 1,863 feet long and 82 feet wide, absolutely fireproof; and the minimum amount of power to be developed will be 60,000

stallation, supplies 200,000 horse-power and is the largest water-power plant in the world. In the power house which it is proposed to erect at the foot of the Des Moines rapids at Keokuk, will be 47 immense generators, of 4,500 horsepower each, working on a vertical shaft, like the generators at Niagara. From the upper end of the power house, the dam proper will extend 6,000 feet, in a grand curve, across the river to the Illinois shore.

this dam, the company has already expended over $50,000 in making preliminary investigations and surveys, and has determined that the project is feasible from both engineering and commercial points of view. The estimated cost of construction is placed at about $10,000,000, and it is expected that the work will be completed within two years.

How is it possible to generate such an enormous power at Keokuk? This will be the first question asked by those of a

practical turn of mind. In order properly to answer it, we must take the reader back to the “good old days" before the railways had honeycombed the country from ocean to ocean. The problem which then confronted steamboat men was how to get over the Des Moines rapids at Keokuk, which begin twelve miles above the point where the proposed dam will cross the river. The river runs through a deep gorge at Keokuk This gorge was cut originally by glaciers, and later deepened by the swiftly flowing stream. The current was so swift and the channel so treacherous that it was impossible for steamboats to go farther north than Keokuk or farther south than the head of the rapids. All freight bound for St. Louis or St. Paul had to be unloaded and carried the distance of twelve miles, both going and coming. Keokuk was at that time the head of up-river navigation, to all intents and purposes.

The river interests finally induced the Government to build a canal from Keokuk to the head of the rapids, which canal, after $5,000,000 had been spent in its construction, was opened to navigation in 1877.

On account of the rapids, too swift for the speediest boats to pass over, the idea of a power dam has been the subject of active consideration by promoters for many years. To handle the project promptly and satisfactorily, the Keokuk & Hamilton Water Power Company was organized six years ago. This company brought the matter to the attention of the Government and of financiers, who have finally
