By comparing the 2d, |d iad :4th Exp^rimeAt^ with 
the loth, nth, and 12th, it appears how much more 
cafily a ?f^3^^<?/2, &c. might bedrawil in rough way es, if 
the fore-wheels were as high as this hinder wheels, and 
it the chills were 6xt under the axis. Such a Wagou as 
this would likewile be drawn more eafily /where th^ 
wheels cut in Giay, ox Sgad, qr Any iorft Grouadi. And 
moreover high wheels would not cut fo deep as low 
wheel$,as £)r. does plaiuiy d^monftrate befides 
fome other advantages which he mentions. 
Low wheels are better for turfiing in a narrow Com- 
pafs than high ones ; But it feems probable that Wagons 
with 4 high wheels might be fo contrived that there 
fhould be no great inconvenience in tha^: refpec9: j at 
kaft liich Wagons as feld<^me haveoccafion to turn Ihort, 
as Carriers Wagons and fuch like. 
Thedifference which you mayobfervein the 8th and 
J I th Experiments, is agreeable to what is faid by S* Ste- 
vinus^y and Dr. Wallis^s ^'yl. that if a Coach ^ ^c. muji 
ie dratr^n over rmgh^ uneven places ^ it ds i^ft to fix the Tra* 
ees to the Coach lower then the height of the Horfes Jhoulders. 
And therefore that is not the beft way which fome Wa- 
goners \xky who fometimes putting their borles iiapairs^, 
h ook the chains of fome of the Horfes to the <:heft of the 
Wagon higher then they need to do. 
14. A Table foot long was fet with one end 1R5 inches 
higher then the other end, and the JViodefl being loaded 
before, lefs weight by <5 ounces drew it up tiie Table 
when the 4 bigger wheels were on, then when a bigger 
amd 2 lefs were on.
