Friday Evening.-The fourteenth banquet to the Trustees of the Missouri Botanical Garden and their guests, provided for in the will of the founder of the garden, will be given at an hour and place to be announced later.

ENTERTAINMENTS.

In providing entertainment for their scientific guests, the local committee has tried to avoid interference with the regular sessions of the association and affiliated societies, and the season of the year at which the meeting is held and the need of a prompt return to their university duties felt by most of their guests have prevented the committee from planning for excursions such as they would have found pleasure in providing under other circumstances. They take pleasure, however, in announcing the following features, which will be more fully detailed in the daily programs.

By invitation of the officers of the Louisiana Purchase Exposition, members of the association and affiliated societies. will, on one of the days of their meeting, proceed in specially provided cars to the World's Fair grounds, immediately after the noon adjournment. On the grounds, they will be tendered a buffet luncheon by the officers of the exposition, after which, in parties of suitable size, they will be taken through the buildings and shown the progress of installation of the exhibits under the personal charge of the chiefs of

departments, under whom the installation is being made.

The chemists are invited to visit the great breweries, either in a body or as individuals, and promised every courtesy in inspecting these and other features of interest to them.

The geologists will receive every possible courtesy from the managers of the smelting and similar establishments of the city which they may find it possible to visit, and it is probable that those who care to do so will have the privilege of visiting the great lead mines of southeastern Missouri, if they can spare a day for this purpose.

The engineers will be enabled to visit the historical Eads Bridge over the Mississippi River, the pumping plant and settling basins furnishing the city water supply, and other points of interest to them, as well as the engineering features of the exposition, of which a special study will be made.

The botanists are invited to visit the Missouri Botanical Garden, either in a body or individually, and are promised every aid that can make their visit pleasurable or profitable.

In addition to the address by the president of the American Association, to be given in the Odeon on Monday evening, it is expected that one other public lecture, complimentary to the citizens of St. Louis will be delivered on another evening by a speaker of international reputation on a subject of both scientific and general interest.

The entertainment committee proposes to furnish luncheon in the high school building, so that members may meet together and without being under the necessity of leaving the building for this purpose. It is expected that courtesies will be extended by a local ladies' club to ladies in attendance at the meetings, and the city clubs, the trustees of the Missouri Botanical Garden, the Academy of Science, and other

local organizations will do what is in their power to make the week a pleasant one to those who attend the meetings.

THE TYPICAL COLLEGE COURSES DEALING WITH THE PROFESSIONAL AND THEORETICAL PHASES OF ELECTRICAL ENGINEERING.*

AT the Chicago meeting of the American Institute of Electrical Engineers held eleven years ago, I presented a paper relating to the subject now under discussion. The proposed subject then apparently created some consternation amongst the members of the committee on papers, who seemed to fear that it was not of sufficient interest to the society. The old prejudice still held against 'college men' in the minds of so-called 'practical men' who had grown influential in engineering practice without having had experience of college life and training. Happily the foundation for this prejudice has ere this been destroyed through the influence of the industrial results achieved by college men. The old prejudice, so far as it now exists, has more particularly drifted into the way of criticism of the engineering schools rather than their graduates, and the character of the schools and the training they afford are
