thoroughly dried. Mix together ; then spread the sand 

 and cinders on the ground and make a hole in the centre, 

 into which pour boiling-hot tar and mix into a stiff paste ;

10. 2 parts lime rubbish and 1 part coal ashes, both 

 very dry and finely sifted ; in the middle of the heap make

 ground should be dry and beaten well. Cover with coarse 

 sand ; when cold, roll well.
