l86 Ohfervations on the conJlruBion of Gates, Majr 



after allowing for the early decay of the fap on the round fide of 

 each poll; infomuch, that a purt of a tree of fmaller dimenfions 

 ini"-hc ferve for the purpose : fuppofe the circumference of a pare 

 of a tree, without the ba k, intended for 4 poits, were only 5 feet 

 8 inches (inllead of 6 feet 3/- inches, which is the circumference 

 anfwering to the diameter of 2 feet) it would contain 16 feet 

 qJ^- inches by culfomary meafure, including the fap, which 

 would be nearly equal in ftrength to 4 polls of 10 inches fquare; 

 for each of fuch polls will meafure in the true way, more than 5 

 feet, and tlie 4 poih M would be reduced 7s in price, or iS 9d 

 each, leaving their value about 8s 3d apiece. 



It would be frivolous to add illuftrations upon queftions, to 

 which fimilar cafes are detailed in every common book on men- 

 fu ration of folids ; but I feel it highly neceflary, to take notice 

 of the outline of thefe fa6ls, which like other parts of the fub- 

 jeft, are not generally pa6lifed upon : and further, fhould a gate 

 of my recommendation be obferved to lodge its head upon the 

 ground, I beg to be coiifidered, as accountable only for the ^ate^ 

 and not for the pojl on vchich it hangs, unlefs my recommendation 

 in that refpect alfo, may have been duly attended to. 



It mull be underftood alfo, that I am eftimating the value of an 

 oak gate-pofl of a certain llrength, and not cavilling about the dif- 

 ference as to the cullomary and true meafure of round timber ; 

 for the market price of timber is confidered as applying to a 

 particular meafure, and taking into the account the wade in 

 converting round timber. 



I have arranged terms upon which the public may be furniflied 

 with exa6l fpecimens of the gate and iron-work recommended, by 

 application to Mr Samuel Lawrence, Black-Smith, or Mr Wil- 

 liam Bucknal Joiner, Shifnal, Shropfliire, who will pay immediate 

 attention to letters, poll paid, containing money to the amount of 

 the order •, and any furplus of a note will be punctually returned 

 with the goods.

I have no hefitation in faying, that I believe the above goods 

 cannot be matched for the fame money * ; even when other work- 

 men 



• Tl;e price of the fet of hanging;s and faftcniiigs for a common field gate, viz. 

 Bj C, D, E, G, and II is only 8s, ai;d the whole jate and iron- work complete was 



calculated.
