Draft or mowinc^ 3ia<]Iim:s, ,}. VV. Samjokn, II. S. — Accoimtsarc 

 f;i\('ii of (lyiianionu'ter tcst.s oftlie dialt of mowing' inacliincs of sevrnil 

 (liMV'icut kiiuls, in ('uttiii<ir grass, clover, and alfalfa, and under varyiiij^ 

 adjustments. The following summary is taken from the bulletin: 



(1) A ditVerence of draft Avas found in mowing machines, hut not great, save in 

 favor of one machine. This dilference seemed to iVdlow speed. 



(2) Tho draft of mowing machines varied in their relations to each other in vary- 

 ing kinds of mowing. This seems to be <lue to speed; therefore they should have 

 two or more pinions. 



(3) The draft of machines varied with the point of attachment for draft. 



(4) Tlio draft was 8.7 per cent greater for a well-sharj>ened sickle than for one more 

 nicely sharpened. 



(5) An old machine w ell repaired drew easier than a new one. 



(6) A 6-foot cutter bar drew easier per foot of cut than a 4i-foot cutter bar, and 

 at a draft less than a ])low carrying an average iunow ; thereibre a pair of horses 

 can draw a 6-foot cutter bar. 



(7) A pitman l)0x set tight gave a draft less than one run quite loo.sely. 



(8) A heavy loss (7.6 jier (M-nt) of force was observed when the truck at the end of 

 the cutter bar failed to roll. 



{[)) AVhen cutter bar is not near right lini- witli pitnun Lod the draft is increased. 



(10) When guards are not true draft is increased. 



(11) When cutter bar is inclined upward the draft is decreasiid. 



(12) The draft was decreased 10 jiouuds by the driver walking. 



(13) When the sections of the sickle do not strike in the center of the guard tho 

 draft is increased.

Steek FEEDING, D. O. XouiJSE, U. 8. (pp. 4-13). — It was the pur- 

 pose of this experiment to compare the effects (1) of corn silajre and hay, 

 an<l (2) of whole corn and corn meal, both witli regard to ffain in live 

 M eight and to cost of lood per pound of gain. Twelve steers, about 1*.J 

 > ears old, were divided into six lots of two animals each, and after a 

 preliminary period (►f a week were fed continutuisly from February 10 

 to April 14 as foUows: 



Lot 1, 37 pounds silage with 12 pounds corn meal. 



Lot 2,37 pounds silage with 12 pouiuls whole corn. 



Lot 3, 37 potmds silage with 8 potinds corn meal and 8 iiounds bran. 



Lot 4, hay od lihitiim with 12 pounds corn meal. 



Lot 5, hay ad lihilnm with 12 pounds whole corn. 



Lot 6, hay ad libitum with 8 pounds corn meal and 8 pounds bran. 



The animals of lots 1, U, and 3 were also given hay ad Ilbition in 

 addition to the silage, but in the rations of the remaining three lots the 

 coarse fodder consisted entirely of hay.
