Dffcription of a neiu Ele&rovieter. 251 



Among the iieweft methods of improving the hofe of fire 

 engines, is that of weaving them without a feam. In the 

 vear 1720 fome of this kind were made at Lcijjtic, of hemp, 

 by one Beck, a iace-weaver, as we are told by Leupoid in his 

 before-mentioned account of fire engines, printed in that vear. 

 After this they were made alfo bv Erk, linen-weave*- at Wei- 

 mar; and at a latter period thev were made of linen at Dref- 

 den, and alfo in Silcfia *•. At prefcnt, Gcgncr and Ehrliholzer 

 have a manufaftory at Bcthnal Green f, where they make 

 water-tight hofe wMthoiit feams. AflTeiror MiJgling has caufed 

 fome of the fame kind to be manufactured on his eftate near 

 Stutfgard on a loom invented bv himfelf, and which are now 

 nfed on many of the towns of VVurtemberg:J:. 1 fliall here 

 take occafion to mention a kind of loom on which Rrauii 

 caufed (hirts without feams to be wove, finiilar to thofe 

 fometimcs brought from India as curiofities, and of which, 

 he gave a particular defcriptioii, with an engraving §. 



I Ihall in the iaft place obfervc, that nolwithdanding th« 

 belief of the Turks in prcdeftination, the ufeof fire engines 

 has been lately introduced at Conftantinople by Ibrahim 

 Eflendi|{.
