USE OF BLOW-PIPE DRYING. 39

 bursts a delicate egg. A suitably bent wire should 

 be provided for cleaning the blow-pipe, which should 

 also be kept corked at both ends, when not in use, 

 to prevent its becoming clogged with dust. 



Blow-pipes are best made of nickel, and the bent

 than the straight. They should be as light as pos- 

 sible, smooth on the outside toward the point, and 

 the orifice should be as large as the diameter of the

 time in blowing large ones ; for eggs as big as a gull's,

Experience will teach one how he may empty the

PERFECTING THE PROCESS. 



After all the contents of the egg have been re-
