one is obliged to pay higher wages to his servants. This fact is well authenticated by a correspondent 

 in the Examiner newspaper of February 13, 1831. (See the examination of Joseph Forster in No. 1. 

 of The Working Man's Companion, and also in Mech. Mag., vol. xiv. p. 323.) 



The mechanical part of the machinery was executed and erected chiefly by Mr. George Miller, now 

 residing near Bagshot. Fig. 1164. is partly a section, and partly a side view ; Jig. 1165. is partly across

 The same letters are applied to the same parts in all the figures. 



8205. Description of the machinery . (figs. 1161. 1165. 1166.) a is an overshot water wheel 15 feet dia- 

 meter, which makes from six to eight revolutions per minute according to the supply of water , on the 

 arms of the water wheel is fixed a bevel wheel, b, of 128 cogs (seven feet four inches diameter), working 

 into the pinion c, of 26 cogs (twenty inches diameter), on the upright shaft d: these wheels are below 

 the ground floor, and entirely hid from the view. 



On the shaft d are two driving wheels, g and/: g is a spur wheel of 119 cogs (six feet two inches am- 

 meter) driving the pinion e, of 22 cogs (fourteen inches diameter) on the shaft h, which leads to the 

 floor above, and turns the upper millstone ; /is a mitre wheel of 40 cogs (two feet diameter), working 

 into two wheels, i and k, of the same dimensions. . . . 



On the same shaft as the mitre wheel, i, is a spur wheel, /, of 200 cogs (six feet eight inches dia- 

 meter), working into the threshing machine drum pinion, m, of 20 cogs (eleven inches diameter) ; the 

 spur wheel, I, also drives a wheel, n, of 39 cogs (twenty-two inches diameter), on the same axis ot which 

 is a small wheel, o, of 26 cogs (ten inches diameter), working into the wheel p, of 121 cogs (three teet 

 four inches diameter), on the axis of the first rake or shaker : the wheel p gives motion to the inter- 

 mediate wheel q, of 72 cogs (two feet diameter), which works into the second shaker wheel ot the same 

 dimensions as the first shaker wheel ;>. . , . , 



On the spindle on which the wheel n is mounted is a small shifting pinion, r, of 17 cogs (seven inches 

 dimeter), working into the faced wheel », on which are two rows of cogs, one of 20 and the other ot 31) 

 cogs each. On the same axis as the faced wheel j is a bevel wheel, t, of 20 cogs (eight inches diameter).
