Biochemic investigations of ropy milk, N. Bociiiccmo {Staz. Sjier. Agr. Hah, 

 27 {1S94), No. 4, pp. 389-36S). — This is largely a study of Bacterium hcaii aud Micro- 

 coccus freudenreichii and of tlieir effect on various solutions. 



A convenient milk sampling tube, M. A. Scovell {Agl. ScL, 8 {1894), No. 6-9, pp. 

 $55, 361). — The apparatus consists of a lonji; copper tube about three fourths inch in 

 diameter, sliding into a cap closed at the lower end. This cap has 3 elliptical open- 

 ings in the sides. In taking the sample the cap is drawn partly off so that tlie 

 apertures are opened. The tube is then inserted in a can of milk and the inner tube 

 pushed down into the cap, closing it, and holding a column of milk. 



This tube was used in connection with the test of breeds at the World's Fair. 

 Tables are given showing its ace .racy. It is claimed that the tube will take a fair 

 average sample of the milk as milked from the cow without mixing, even after stand- 

 ing some time.

AGRICULTURAL ENGINEERING. 



Massachusetts College barns {Massachusetts Agl. Col. Bin. 1894., pp. 

 44-51). — The new fiirm buildings of tlie Massacbusetts AgTicnltiiral 

 College, recently completed at a cost of about $35,000, consist of a horse 

 barn, 41 by 91 ft., and a large storage aud cattle barn. These buildings 

 are frame with steel rooting, are lighted by electricity, and were con- 

 structed with special reference to the welfare of the animals aud the 

 saving of labor in feeding the stock aud haudliug the manure. 



The main part of the cattle barn is 141 by 01 ft., aud consists of a 

 basement aud two stories. The toi^ographical condition of the site 

 allowed a driveway of an easy grade to be constructed at the east end, 

 leading to the upper floor, 22 ft. above the main floor. This enables 

 the storage of hay, silage, grain, stable absorbents, aud bedding with 

 the minimum amount of labor. At the western end 20 ft. of the loft is 

 floored over so that wagons can be turned around and driven out by 

 the east door, as the floor at the west end is 31 ft. above the ground. ' 



On the right of the interior driveway, which is 14 ft. wide, are traps 

 comniunicatiug with large bins for grain, a set of Fairbanks hay scales, 

 and ample space for the operation of heavy barn machinery, where are 

 placed a 15-horsepower electric motor, silage cutter, cornsheller, grain 

 mill, thresher, etc. Further on are 3 silos which extend to the base- 

 ment and will hold 425 tons of silage. The rest of that side, together 

 with nearly all of the space on the left of the driveway, is occupied by 

 haymows, in which 240 tons of hay can be stored. 



The folding door shown on the south side near the east end, opposite 

 which is a similar door, is ax^proached by a very easy-graded driveway 

 held by a curved retaining wall, and admits to a floor 11 ft. wide and 

 12 ft. above the main floor. Below this cross tloor is a very capacious 

 vegetable cellar, reached by traps in the cross floor aud through a
