 sat, 



AT a time when the attention of eco- 

 nomiits has bten drawn particularly 

 t(j the conltruction of roads, it may be 

 proper to acipiaint your readers with the 

 opiiaon of the late illuftrious Bakewell, 

 of Dilliley, on this important fubjeCt. 



Mr. Bakewell \\\'cd to maintain, as the 

 refult of many years attentive obferva- 

 tion, that L!:e belt roads are tliofe which 

 are watered by a natural flream, that 

 they are always diltniguilhcd by a hard 

 bottom, are never cut up, and leldom or 

 ever require repair. lie would quote, in 

 )iis eujphatic manner, pieces of road in 

 Various parts of the kingdom, whicli were 

 accideiittdly walhcd in this manner; and 

 the obvioufuofs of the fact never left ai;y 

 room to difputc his principle. 



A little conljderation will explain why 

 a walhed road mull neceflkiily be better 

 than all others; the argillaceous or clayey 

 matter is dilTolved by the ftreaui, and 

 earned off as fall Jis it may accumulate, 

 swid the vitreous or llony particles and 

 fubllances remain; or, in other wordB, 



that matter wliich fpoils and ruiusall 

 roads is wallicd away, and that is oul» 

 lelt which tonus their true bali.s. 



Bakewell was, however, not a man 

 who contented hiinlelf with mere hypo- 

 thetical rcafonings, and having ellablilhed 

 ajull principle, he next conlidered of tlitf 

 means of applying it to the Luluiefs uC 

 life. 



He, therefore, laid it down as a prin- 

 ciple of the fcieuce of road-making, that 

 every road Ihould fall laterally, and be 

 concave tranfverfely ; and that Itreaiua 

 of water Ihould be turned upon iJieia 

 from time to tune, fo a» to hii the ruts, 

 and Carry olf the argillaceous or clayey 

 matter. 'I'helc llreams might generally be 

 produced from fprings, or water might 

 Lie accumulated m relervoirs by the road 

 iide. 



In my opinion, thefe ideas of Bake- 

 well delerve the attention of the legilla- 

 ture, and of all perfons luteielted ni the 

 conltruction of roads. My own oblerva- 

 tions, m the courie of much travellmj;, 

 have coiiiirined the jultnelij of his prin- 

 ciple, and our old-ialhioaed convex 

 loads, of whatever materials they are 

 made, are public nuifcUices which ought 

 no long'er to be tolerated,

SIE, 



Mil. Walker having obferved that 

 I'everal errors refpetiing the ef- 

 tects of his dilfereiil Frigoniic iVlixtures, 

 have appeared m various publications o* 

 the tint refpeclability, owing to the ta- 

 bles given in tiiole works being iucor- 

 red copies of the tables exhibited in the 

 different volumes of the Philolbphical 

 TranfaCtions, in which they ongmally 

 appeared : begs leave to obferve, thai 

 thefe errors leein to have arifen from 

 the minus characters in the original ta- 

 bles having been overlooked; thus, for 

 intlance, by referring to the table of 

 frigoniic mixtures given in the Philolo- 

 phical Traiilactions for 17;95, page 279*, 

 it will be found that from tliC third mix- 

 ture to the tenih the mi/ms marks are 

 ufed; wlicrcas, in the copies, alluded to, 

 they are all onutled. 



This error in one inllance, vie. in the 

 ninth mixture, is no leis than forly-twn 

 degrees ; the refult in that inllance he-
