STATUE OP JOAN OF ARC. | ^5 



the pfpes for the vents and for the entrance of the fiifed metal. 

 The earth ufed forenclofing the mold ihould be firll fkreened, 

 and then laid on equally in the excavation. After eacli courfe 

 is raifed to a thicknefs of t-liirty centimetres, ( l toot) it is beaten 

 down till it is reduced to ten. 



After this there on]y remains to build the bafon for the re- 

 ception of the melal, called the echiiio. 



In enumerating the operations neceffary for the method of Enumeration of 

 calling in fand firfl mentioned, the authors of the report ftate^^'^ various ad-

leis than twenty-eight, each or which they particularize; but ^igcy. 



as thefe operations may readily be counted from the relation 

 already given, this catalogue is not inferted here. They alfb 

 remark, that the laying on the wax on the pieces of the mold 

 takes up much time, as does likewife the preparation of the 

 potee: that in the firft method the circling with bands of iron 

 is entirely avoided, and the building of the pallages for the 

 lire, which are very expenfive: liiat likewife the molding 

 and fetting up of the vaft number of pipes and vents is faved 

 in it ; and in the drying of the work the economifing of fuel 

 is greatly in favour of the firft method, for in it thefe operations 

 are performed in a (hort time with a very (mail fire, which in 

 the other method require at leaft three weeks and a powerful 

 Iieat : that in the repairing of the wax the ftaluary nuift work 

 with his own hands : and that in taking out the ilatue when 

 cafl, there is vaftly lefs trouble in the ilrft method. 



The authors here defcribe the metliod of ercfting the fur- 

 nace for fufing the metal for the ftatue of Joan of Arc ; but 

 as it was conftru6led to burn wood, which fuel is not ufed in 

 our founderies, and as the defcription would be on other ac- 

 counts of but little benefit to our arlifts, it is omitte-d, 



It is only neceflary to flate, that the place wliich contained 

 (■he fufed metal was at fuch an elevation, that, when (he Hop- 

 per which retained it was driven in, it might fl' vv' f.eely into 

 the €chino throogh the paflage prepared for it. 



The mold for the ftatue was partly buried in the earth, fo as The mold of the
