and fresh swill, fed with a suitably prepared ration of other articles 

 of food to healthy cows, having clean, roomy stables, and plenty of 

 exercise, is injurious to the milk, but it is this : Is wholesome milk 

 produced by feeding swill under the conditions in which it is fed in 

 practice, and must be fed in order to make it a profitable industry ? " 

 And finally, as Professor Rohe so well expresses it, " a scientific 

 solution of the question will not be furthered by prejudiced appeals 

 or unreasoning denunciation. Patient investigation, keeping in 

 view all circumstances of the question, and avoiding all one-sided- 

 ness in considering the matter, will alone bring about the object 

 desired." 



With these suggestions to those having in charge the experi- 

 ment stations, we leave the subject with our readers. We shall be 

 glad to record any observations or experiences which any one may 

 send us in the future ; so that, even if public interest cannot be 

 sufficiently aroused to bring about a proper investigation of the 

 subject at the present time, it may, by a reminder from time to 

 time, be kept alive until the demand for such an inquiry becomes 

 irresistible. 



up to the present time, about two hundred students. To prepare 

 for the incoming class of 1S87, therefore, it became necessary to 

 still further extend its buildings. It was thought advisable to more 

 than double the size of the wood-working shops, to increase facili- 

 ties for instruction in the other shops, and to secure fifty per cent 

 more space for drawing-rooms. The freehand-drawing class alone, 

 this year, which includes students from several other courses not 

 included in the mechanical engineering departments, is expected to- 

 number over two hundred and fifty students, and occupies two 

 floors of the main building. The wood-working part of the estab- 

 lishment must accommodate between one hundred and one hun- 

 dred and twenty-five men, and the other shops as many more. To--" 

 meet this emergency, a new building was planned, into which all 

 the laboratory apparatus used in either instruction or research could 

 be removed ; thus giving ample space, for the present at least, for 

 the extension of the shops, by giving to them the considerable space 

 so vacated, while the remainder of the new structure could be de- 

 voted to the purposes of the departments of drawing and machine 

 design.

THE SIBLEY COLLEGE EXTENSION, CORNELL UNI- 

 VERSITY. 



The extraordinarily rapid growth of the Sibley College of Cornell 

 University since its re-organization and expansion of two years ago, 

 with the introduction of the course and department of mechanical 

 engineering under Professor Thurston, the extension of its shops 

 and department of the mechanic arts under Professor Morris, and 

 the formation of a carefully planned department of the graphic arts 

 under Professor Cleaves, — all under the general direction of Dr. 

 Thurston, — has compelled a corresponding extension of the ac- 

 commodations for class and lecture rooms, and especially for shops 

 and drawing-rooms. Two years ago, before this re-organization 

 had taken effect, the number of students taking this course was 

 very small, varying from twenty to thirty, perhaps. Last year the 

 freshman class, including mechanical engineers in regular course, 

 in electrical engineering, and special students with the resident 

 graduates, numbered above eighty. The number of applicants this 

 year is so large that the limit for the entering class is necessarily 

 fixed by the capacity of the shops and buildings, including the me- 

 chanical laboratory. It is probable that the numbers received in 

 all classes will exceed two hundred and fifty. When all classes are 

 filled on the basis now taken, the college will number something 

 over three hundred students. 



But it was originally designed to accommodate very small 

 classes ; and, notwithstanding the fact that within a few years it 

 has been more than doubled in extent, it could only accommodate. 



The engraving on the next page shows the extent and arrangements 

 of the departments of the original group of Sibley College buildings. 

 The main building is seen at the front and left ; while beyond it is 

 the laboratory building, in which instruction in chemistry and 

 physics, and the principal part of the tuition and practice in elec- 

 trical engineering, are carried on. The dynamo-room is in the rear 

 of the main building of Sibley College, and contains a considerable 

 number, and hardly less variety, of dynamo-electric machines, used 

 in the course in electrical engineering principally. The lower floor 

 of this building is devoted to the purposes of library and reading- 

 room, museums, a lecture-room for the junior class, and the rooms 

 of the professor of the mechanic arts. The second floor contains 

 two large drawing-rooms, the lecture-room of the professor of me- 

 chanical engineering, and the rooms of the director. The third 

 floor is occupied by the rooms of the professor of drawing, — 'his 

 office, lecture-room, and two large drawing-rooms like those below. 

 All these drawing-rooms are expected to be occupied by the lower 

 classes ;' while the senior and junior-classes will have their drawing- 

 rooms in the new structure, now just occupied, which building will 

 also accommodate the resident graduates, professors, and others 

 coming to Cornell for advanced work in this department of the uni- 

 versity. 



The accompanying plans present the arrangement of the build- 

 ing forming the last of the Sibley College extensions, and now just 

 completed for occupation at the beginning of the college-year 1887- 

 88. It is calculated to be of sufficient size to accommodate the ac-
