Opinion of the The Board are of opinion, that the refult of the Infpe6lor's 

 Boardof Trade, gjjpgrj^gj^^g will afford very acceptable information to the

be aoceptable to calico-prnUers m England ; and, if their operations (houid 



calico-printers, prove his ideas to be well founded, the plant may prove a 



the E. I. Corn- valuable acquifition to the raanufa6lurers of Great Britain, 



pany» and alfo an article of commerce from the coaft particularly 



ufeful, as there is a want of coaft articles of low value, as well 



light, as a fufficiency of ponderous, to make up a proper cargo 



for a large 111 ip, without fwelling its value to too great a rifk,

Advantages to JtLVERY drop of water that falls may be confidered as a 



"Sb ^TJH^i ^^T^ natural power capable of doing foriie work ; and it would be 



produdive of confiderable benefit in many domeftic and ma- 



nufaduring exigencies, if fmall ftreams and currents defcendr 



ing along the fides of hills, or even through the meadow?, 



were employed, by the application of limple machinery. 



Small mills In to affift the labours of man. I am informed that numerous 



Portugal. ii^jg j^ijjg £qj. grinding corn are diftributed over the face of 



the country, in Portugal, upon very inconfiderable rivulets ; 



where they not only add to the general produdl of human 



work, but may alfo perhaps tend to equalise the price of grain 



Avery fmall to the confumer. And indeed if it be confidered that a fmall 



brook may do ftream of about a yard wide, running over an obftacle to the 



depth of an inch, and having fpace to defcend through twelve 



inches, would do half as much work in the 24 hours as a horfe, 



whether in grinding corn or turning an engine, or raifing water 



for ufeful purpofes, we Ihall be ftruck with the neceffity of 



enquiring whether any falling water whatever fliould be fuf- 



fered to defcend without due employment in its courfe.
