The use of branding- fluid, (i. H. Trite {Arhona Sta. Bui. 47, pp. .i]4-:n7). — A 

 fluid which was tested for branding cattle, in the author's opinion, did not give as 

 satisfactory results as are generally obtained with the branding iron. 



The food cost of raising calves, C. L. Beach {Conmrticitt iSturrs >it<i. Rpt. 1903, 

 pp. lS7-l'.ii>, Jigs. 4- ) — I* or several years records have been kept of the feed con- 

 sumed by heifer calves from birth until about 6 months old. They were fed whole 

 milk at first and later skim milk. Rowen hay was always supplied and grain in 

 some cases during the last 2 months of the feeding period. 



The gains noted, 1.25 lbs. in 1900 and 1.31 lbs. in 1899 per head pt-r day, were 

 regarded as satisfactory' for animals designe<l for the dairy henl. Tlu^ cost of feed 

 required for 6 months' feeding was 44.6 cts. per week in one year and 47.;! cts. in 

 the other. On the basis of observed <lata the cost of raising calves from l)irth to 

 maturity (a little over 2 years) was $o.3.20. 



"Kalberrahm" -with skim milk as a milk substitute in calf feeding, J. 

 K.Xi'PKi.i {Laiidir. Jahrh. Schirelz, 17 [1903), No. 8, pp. 40I-4I8, Jigs. ;J). — As shown 

 by feeding experiments with calves " Kalberrahm," a commercial feeding stuff 

 designed as a substitute for milk fat, did not give as satisfactory results as whole 

 nulk, 14.54 liters of "Kalberrahm" and skim milk being required per kilogram of 

 gain as compared with 10.9 liters of whole milk or 10.4 liters of skim milk. When 

 the quality of the flesh was taken into account the results, the author states, were 

 even more unfavorable to the " Killberrahm" and skim milk. 



Live stock. Steer feeding, II. K. STocKBKnxiE {Florida ,St<(. Rpt. luu.l, pp. 

 l-i-W). — Notes are given regarding the live stock kept at the station, and feeding 

 experiments with steers are briefly rei)orted. Two grade oxen, fed chiefly on velvet- 

 bean forage, made a gain of .3.5 lbs. i)er head per day, as compared with 2.17 lbs. 

 made by a pair of native oxen under similar conditions, the profit in the 2 cases 

 being $7.61 and $7.31 per ox. The time covered by the test was 60 days. 



In a second test velvet-bean j)ods were compared with cassava and cassava pulp 

 (refuse from a starch factory). Lot 1 (2 steers) was fed 3 bu. of velvet beans in 

 pods; lot 2 (3 steers) was fed 30 lbs. of cas.sava and 5 lbs. of cotton-seed meal; and 

 lot 3 (3 steers), 18 lbs. of cassava pulj) an<l 5 ll)s. of cotton-seed meal, all the animals 

 receiving cowpea-vine hay in addition to the feeding stuffs mentioned. In the 60
