ENIGMAS AND THEIR SOLUTION. 57 



twilled square, to the point where the disc 

 pattern begins ; the new cards would then 

 begin to throw up the new pattern, while 

 the loom would go on weaving as before 

 the twilled square on each side of the disc, 

 until the cards of the shell pattern suc- 

 cessively intervened : if the disc extended 

 wholly across the square, the cards that 

 form the square would gradually be wholly 

 superseded. It is to be noted that the cards 

 that produce the pattern on the disc do not 

 simultaneously supersede those that weave 

 the square, nor does the change in texture 

 run in a straight line across the web, but 

 gradually as the cloths differ. 



If a new tablecloth is to have a different 

 kind of square, the specific variation between 

 it and the first would be greater, and the 

 new adjustment of the loom would supersede 

 the old at an earlier stage when the border 

 was completed. 



If a simpler tablecloth i.e., less specialised 

 than the first is wanted, either the centre 

 pattern or the twilled square, or both, may 

 be dispensed with, and the correspond- 

 ing arrangements of the loom would be 

 omitted.
