■f^I. BRIDGE OF A NEW CONSTRUCTIOV. ICS 



' nny repairs- ^ifth^ if x\\z timbers fliould not even escee'* 

 twenty feet in lenj^th. the bridge may be neverchelef* 

 conftrucled with the fame folidity. Sixth, a fufHcient nuri- 

 ber of figures, to be reprefented on twenty pbtes, (hall be de- 

 livered alonpi with the work, which (hall give fuch a plain re- 

 prefentalion of the work in all its parts, that an experienced 

 architect lliall be able, by the help of thefe, to direct the 

 carpenters with the utmoll certainty to execute every part 

 of it. Seventh, to e^pofe the fide of it as little as r-uTible co 

 tiie force of llorms, care has been taken to give to this 

 bridge a very low roof^ but which is not the lels conlidera- 

 ble for that, and, which is peculiar to itfelf, in place of pufii- 

 ing outwards as other roofs generally do, this anfwers the pur- 

 poi'e of an anchor which tends to keep the bridge together 

 at the top, and has at the fame time a (utiicient height t'> 

 make the water run as much as is necelTary. Ei^b'% 

 I' can aiTert that this fort of bridge is lingular in it> 

 kind, on which the heaviell burdens may be carried with 

 fafety. There are a great many bridges in Europe of a 

 confidcrable length, but not of fuch a length without pil- 

 lars or fupports •, and there are likewife none to be fouud 

 •without a good buttrefs, and guards, and ftill lefs conltrutl- 

 <d with a (imple foundation without abuttment j not to 

 mention the continual repairs which this new method 

 would fave altogether. Ninth, we (hall give with the en- 

 gravings and defcriptions an eftimate of the expence, as 

 if a bridge were to be built at Hanover four hundred 

 feet long, by thirty eight broad. 



" I receive the fubfcriptlons myfelf ; but I beg the ama- 

 teurs to fend their letters free ; and as foon as there (h.iU 

 be a futliclent number of fubfcribers, I will put the work 

 in hands, and make the plates be engraved. The price of 

 the fubfcription is three I.ouis d' ors, each worth (ive Ger- 

 man crowns, two of which (hall be paid at the time of 

 fubfcription, and the third on the receipt of the work. 

 The names of the fubfcribers (hall be put at the beginning 

 of the work j any one who takes ten copies (hall get the 

 eleventh gratis.
