ward and holding an oil stone first against one side and then the other. 

 Next the saw is to be tried, to see if it is just right. It ought now to cut 

 rapidly, straight and smoothly — every cut a glue joint. If it does not 

 run straight — either drawing the board away from the gauge or wedging 

 it so tightly as to stop— the trouble is either with the saw or the guage. 

 Look at the end of the saw kerf, if it is pointed on one side or the other, 

 the teeth on the pointed side are too long, and they must be filed again 

 and thus shortened. If the kerf is square across, the trouble is with 

 the guage. It must be made exactly parallel with the saw. If the 

 further end is nearer the saw than the other, the piece will wedge ; if 

 nearer, the work can not be held close to the guage. The table should 

 be raised so that the teeth just reach through the piece sawed. 



There ought to be a pretty heavy fly wheel connected with the sawj 

 and as much difference between the size of the driving wheel and the 

 pully of the mandrel as convenient, so as to obtain as much speed as 

 possible; But any arrangement of geared wheels to obtain speed is not 

 satisfactory. 



FOUL BROOD. 



This is a disease which, as its name indicates, attacks the brood, and 

 soon destroys a colony by preventing any brood from coming to 

 maturity. We are thankful that personally we know nothing of this 

 disease. Those who have suffered from it pronounce it very fatal, though 

 there seems to be several phases of the disease; some far more fatal than 

 others. The disease is contagious, like small pox or cholera and like 

 these is propagated by very small spores or germs, which attack brood and 

 destroy it. To check or cure this disease the fungus growth must be 

 destroyed.
