insure a good heat on the point, which is thicker than 

 the mouldboard and therefore would not be hot enough 

 in the time the other parts get hot. 



When a mouldboard is worn out on the point a patch 

 can be put on, if the mouldboard is not too much worn 

 otherwise. Cut a piece of soft center steel to fit over 

 the part to be repaired. Draw this piece out thin 

 where it is to be welded to face of mouldboard. Hold

this piece in position while taking the first weld, with 

 a pair of tongs. Weld the point first, then the edges, 

 last the center. The patch should be welded to face 

 of mouldboard. When the last weld is taken place the 

 mouldboard face up, with some live coal over it, in the 

 fire ; use borax freely, and, when ready to weld, weld 

 the patch while the mouldboard is in the fire, using a 

 ^ rod of round iron as a hammer with one end of it 

 bent for this purpose. When the patch is thus welded 

 in its thinnest place then take it out and weld on the 

 anvil. In heating for the weld never place the patch 

 down towards the tuyer, for there the blast will make
