THE3 LABORATORY. 



^^'itll the above ('oni})rebensive view of bacteriology in mind, — such 

 a view as may be found typically represented in a large numter of 

 laboratories in the Avorld— the plans for a new laboratory were under- 

 taken. Two distinct objects, primary in a.11 of our undertakings, and 

 fundamental to the growth of this science, should be kept in mind in 

 <'onsid(n'ing these i)lans; the one, research, as represented as a division 

 of the experiment station, and Avhicli is so full of promise for the future; 

 tlie other, class work, which by means of disseminating knowledge which 

 we already have at hand is essential to progress in a science. 



As the needs of this institution were surveyed, the conclusion reached 

 indicated that each ])urpose demanded about equal attention. Work, 

 as we find it in an agricultural college, must not only be purely scien- 

 tihc but must also ])ass to an issue and application; otherwise it fails 

 of the mark. Therefore, in order to carry out all of our scientific en- 

 deavors to a point where they cai^ be taken up by those who deal in 

 tlie practical ])hases of agriculture, it became evident that rooms or 

 facilities must be ])rovided for the study of communicable diseases, of 

 bacterial plant diseases, soil problems, dairying, fermentation, — in short, 

 any bacterial problem known to agriculture or domestic science. In 

 erecting a building that shall include this broad scope, a stable is neces- 

 sary, a small greenhouse for bacterial plant and soil studies, a soil 

 r,oom for soil storage and filter paraphernalia, a dairy room, a tempera- 

 ture room, and, in short, rooms where the science may be applied to 

 actual problems which are, in one way or another, connected with the 

 jiractical workings of the farm or of the household. Accordingly, it will, 

 be seen that the range of the work is vast; consequently, in order to 

 make the science useful and valuable, the laboratory must be adapted 

 to meet the demands which the farmer or the housekeeper jnakes upon it. 



It should not be necessary that the plans of the laboratory be dis- 

 cussed in detail, for the illustrations following this report will clearly 

 show Y^'hat each room stands for and will suggest possible uses. Any 

 one who may review these plans critically should bear in mind that it 

 is impossible, in erecting a laboratory, to have everything as he would 

 desire it, simply because there are so many conflicting ideas, and often, 

 if one idea predominates, another must be eliminated. For instance, 

 it is impossible to make all of the laboratory rooms face the north and 

 east, however desirable. 



A general description of the laboratory ma}' help to convey a full- 

 ness to the meaning of the photographs and clear up points which other- 

 wise would l)e indistinct. 



The building is made of brick, the outer walls having a two-inch air 

 space, primarily to arrest moisture, heat, and cold. Many of the inner
