Dynamometer tests with wagons, J. W. S^vnijoun, B. S. — Ac- 

 counts are given of tests with reference to tlie draft of wagons as 

 alfected by tlio distribution of the load, the height of the wheel, the 

 length of hitch, loose vs. tight burrs, lubricants, style of construction 

 of the wagon, different kinds of roads, and dillerent grades. The fol- 

 lowing summary is taken from the bulletin : 



(I) Wticn tho lo.id was pl.iced over tho hind wheels it drew 10 per cent, e.isier th.an 

 wlien it was pl.ieed over the front wheels. 



(•J) 'J'ho hind wheels drew 2'.iM per cent easier o\er an obstacle I? iiu^lies liiijh than 

 the front wheels. This was when attachment of the force was directly applied to 

 each set of wheels. 



(:i) The hind wheels when drawn over an obstacle by tho nsu.al hitch drew only 1.2 

 pel- cent easier than the fore wheels. 



^'1) When the ends of the wagon were reversed and the draft was applied directly 

 to the hind wheels it drew nearly 5 per cent easier. 



(.')) Tho incline of tho reach towards the front wheels, as now put in, canses the 

 wagon to draw harder than it shonld. 



(()) Lowering the reach or the point of application of force on the hind wheels 

 malcrially decreases the draft; therefore the reach shonld rim horizontally or on an 

 upward incline from the rear to tho front wheels. 



(7) Higher front wheels will reduce draft. 



(8) Tlio change of the angle rtf draft as a))pli('d from the end of the pole, varied the 

 draft very markedly and tho relation of the draft of the front to the rear whecds. 



(9) A long hitch or such a hitch as occurs when lead horses are used, increases 

 draft on account of tho angle of tho hitch. 



(10) Loose buiTS with one half or more inches play lessen tho draft of the load by 

 4.5 per cent. 



(II) Little difl'erence was found between the draft of three wagons. 



(12) Draft varied with the v.aricties of grease used, from nothing to 17 per cent — 

 lard proving the best or practically the same as a manufactured axle grease and bnt 

 a little better than cylinder oil. 



(13) Tho draft of varying roails and condition of roads varied very m.irkedly, 

 being between the best and tho poorest cl.asses of local roads nearly 300 per cent in 

 difl'erence. In thi« trial neither the best nor the poorest roads were availal)le — only 

 Buch as arc found in country towns. * * * 



(14) There is a decided opportunity for im])rovement of our wagons.

 cows exhibited at the Champlain Valley Association Fair, at Burlington,
