limited upon such matters as the maintenance and pro-

and the application of scientific principles to our choice of diet.

So important and widespreading are the problems involved in
these subjects that the force of the Department and the authorities
of the l'niversity feel that no higher duty devolves upon them than
the dissemination of such knowledge as will aid in their solution.

The following publications have been already issued:

issued:

La Fayette, Ind., January 5, 1898.
With the establishment of courses of study in Sanitary Science at Pur-
due University, and the complete equipment of laboratories necessary for
the carrying out of such courses, the University authorities are enabled,
in addition to regular work in instruction, to offer the services of these laboratories to the physicians of the State for the diagnosis of tuberculous sputum, and of malarial and typhoid blood, together with other purely bacteriological examinations. These will, for the present, be undertaken and a report thereon made without charge, subject to the conditions named below:

Since it is not our purpose to enter into any commercial enterprise, but rather to perform a public service, it is necessary to limit our efforts to those cases which may possibly have an immediate relation to the public welfare. For this reason it is thought best for the present to operate through official bodies. We shall therefore examine such specimens as may be sent us by physicians with the endorsement of the secretary or president of a local medical organization.

All communications and all material should be addressed to Severance Burrage, S. B., Instructor in Sanitary Science, Purdue University.

JAMES H. SMART.

President Purdue University.

As a result of this circular we have, at the request of physicians in various parts of the State, made a number of most thorough and careful examinations. These have, so far, averaged eleven per month.

It will be observed that these examinations are made only when the cases are of sufficient magnitude to involve the public welfare. It is but just to say also that, while in doing this work Purdue is performing a public service, these examinations afford at the same time the very best possible discipline and practice for our students. Research in One of the most important of our research labora

Railroad tories is found in our Railway Engineering DepartEngineering

ment. While much of the work of this laboratory is necessarily of a routine character, yet its facilities are such that the instructors are able to conduct original investigations bearing upon railroad construction and practice. In the possession of a locomotive testing plant, which is not duplicated elsewhere, the University enjoys unusual facilities for such investigations. No complete outline of this work can be presented here, but its character is well disclosed by a list embracing some of the investigations, which have been of such importance that the results have been published in transactions of scientific societies and other scientific publications, both in this country and in Europe. Such a list is as follows: 1. The Superheating Effect Derived from the Steam Pipe within the

Smoke-Box of Locomotives. 2. An Experimental Study of the Action of the Exhaust Jet.

3. The Performance of a Four-Cylinder Compound Locomotive. 4. Tests of a 60,000-Pound Car Axle. 5. An Investigation of Air Currents About a Moving Car or Train of

Cars. 6. A Study of the Atmospheric Resistance to the Motion of Railway

Trains. 7. An Experimental Study of the Effect of the Counterbalance in Lo

comotive Drivewheels upon the Pressure between Wheel and

Rail. 8. The Effect of Iligh Rates of Combustion upon the Efficiency of

Locomotive Boilers. 9. The Performance of Locomotive Schenectady at Different Rates of

Speed. 10. The Effect of Changes in Cut-off on Locomotive Performance. 11. The Efficiency of a Locomotive under Different Steam Pressures. 12. The Performance of Locomotive Schenectady under Different De

grees of Throttling. 13. The Effect of Inside Clearance on the Efficiency of a Locomotive. 14. The Effect of Outside Lap on the Efliciency of a Locomotive. 15. Spark Losses From the Stack of a Locomotive. 16. An Experimental Locomotive. 17. Test of the Locomotive at the Laboratory of Purdue University. 18. New Forms of Friction Brakes. 19. An Apparatus for Determining the Form of the Exhaust Jet. 20. Limitations of Speed of Railway Trains. 21. Grate Areas, Rate of Combustion and Heating Surfaces. 22. The Effect upon the Diagrams of Long Pipe Connections for Steam

Engine Indicators. 23. Speed of Rotation for Locomotive Engines. 24. Paper Friction Wheels. 25. The Engineering Research Laboratory in Its Relation to the Public. 26. Tests of Wrought Iron Car Axle. 27. Tests of a Balanced Locomotive. 28. Form of the Exhaust Jet in the Smoke-Box of a Locomotive. 29. Compressed Air in Railroad Shops.

These and other publications have been widely copied and commented upon in technical papers all over the world. During the past five years no fewer than three hundred columns of reprint and comment have appeared in such publications. Experi

There is still another department of the University, mental Ag. the work of which is of more importance than any I riculture. have mentioned, namely, the Department of Experimental Agriculture.

This department consists of an experimental farm and a series of laboratories equipped at the expense of the United States, known as "The United States Experiment Station," although they are under the control of the University authorities and form a part of the University system.

The expense of this department is borne entirely by the United States, the money being used for research and publication only. The corps of experimenters, whose names are found under the title “Station Staff,” are members of the Purdue faculty and do regular instructional work for a part of their time. The greater part of it, however, is spent in research work—the proper proportion of their salaries being paid from the general University fund and the Hatch fund.

A brief survey of the history of this department during the past ten years will show that it has accomplished a large amount of valuable work.

We are specifically enjoined by law to conduct agricultural research in laboratory and field and to publish the results thereof in quarterly bulletins, which are distributed gratis among the farmers of the State. During the period named fifty-four regular bulletins have been so distributed. These have conveved useful information on subjects that are supposed to be of special interest to farmers, stock raisers, horticulturists and dairymen.

In addition to these bulletins, we have, during this period, published sixty newspaper bulletins upon similar topics. These have generally appeared in our leading newspapers, thus securing a very wide circulation.

The aggregate number of bulletins published in the past ten years amounts to more than five hundred thousand, or fifty thousand per annum, and the total number of pages distributed amounts to over nine millions, or nine hundred thousand annually. The following are the exact figures:

The question of establishing the sugar beet industry Beet Sugar

in the State of Indiana has absorbed a large portion of Industry.

Professor H. A. Huston's time during the past ten

years. He has established and supervised one hundred and fortyone subsidiary stations; has sent out seven hundred and forty-four samples of seed; has made nine hundred and three analyses for the determination of the quality of the sugar beet; has published seven bulletins, and has delivered forty-five lectures on this subject.

The following is a summary of the sugar beet work, 1888-1897, under supervision of Prof. Huston:

[blocks in formation]

The growth of this work may be seen from the fact that already, during the present year, we have sent out over 1,700 pounds of seed to 744 different stations, from a large per cent. of which we confidently expect returns and for which we must perform the necessary chemical analyses. In addition to these samples, twentyfive are now being tested on the Purdue farm. The work of this year is not included in the above summary.
