 The images appearing here are the best quality 
 possible considering the condition and legibility 
 of the original copy and in Iteeping with the 
 filming contract specifications. 
 
 Original copies in printed paper covers are filmed 
 beginning with the front cover and ending on 
 the last page with a printed or illustrated impres- 
 sion, or the back cover when appropriate. All 
 other original copies are filmed beginning on the 
 first page with a printed or illustrated impres- 
 sion, and ending on the last page with a printed 
 or illustrated impression. 
 
 The last recorded frame on each microfiche 
 shall contain the symbol — »■ (meaning "CON- 
 TINUED"), or the symbol V (meaning "END"|. 
 whichever applies. 
 
 Maps, plates, charts, etc., may be filmed at 
 different reduction ratios. Those too large tc be 
 entirely included in one exposure are filmed 
 beginning in the upper Itft hand corner, left to 
 right and top to bottom, as many frames A 
 required. The following diagrams illustrate the 
 method: 
 
 Les images suivantes ont M reproduites avac la 
 plus grand soin, compte tenu de la condition et 
 de la nettet« de i'exemplaire film*, et en 
 conformity avec les conditions du contrat de 
 filmage. 
 
 Les exemplaires originaux dont la couverture an 
 papier est imprim6e sont film<ks en commjn^ant 
 par la premier plat et en terminant soit par la

 fiiii be left fur sevenil liayM until it is thoroiijfhiy dried so iiiucli 
 the lietter, iis it is found tliiit the siiw works more easily in 
 thorou;;lily ilry plaster. The stone is sawn directly through 
 the plaster which embeds it in the line previously marked on 
 the board, and a second cut is made throiigli the plaster between 
 tlie stone and the heel of the hor.seshoe. If the stone is very 
 large and hanl, the Iward may U' fastened in a vice, and tlrj 
 saw cut made through the Ijoard al.so. This .serves very 
 materially to stea ly the .^aw. This section thus liberated can 
 then be readily detached from the lx)ard and will be found 
 to contain one-1-alf of the stone, which '.in I asily lifted 
 
 out of the embedding plastei'. part of which may lie cut 
 away (Fig. 2 Ft. The removal of the stone from the piaster 
 is facilitated by i)lnnging the wliole into hot water lor a 
 few moments, when the ])urat!'n wa.x becomes softened iuid 
 the stone can thu.s be .'asily separ-ited from the plaster. The 
 last trace of wax is then melted otl' liy holding it under a hf)t 
 water tap, or putting it into a basin of hot water for a few 
 moments. The cut surface of the stone may be polished rapidly 
 and easily by grinding it on a ground-gla.s' surface. In theca.se 
 ul' ver}- hard stones the |iolishing process is facilitatecl by using 
 powilered ])umice stone or emi'ry, (hough this is seldom 
 necessary. In order to get a highly polished surface the 
 stone should tinally be rubbtij on dry. plain glass, .ind
