SUGGESTIONS FOR FURTHER WORK OUT OF SCHOOL 



It is hardly necessary to point out that all the subjects which are 

 used for continued observation may be watched with advantage 

 during the time which elapses between two lessons. It is necessary, 

 almost, if the process which the silkworms go through of changing 

 their skins is to be seen, for the pupils to watch them from day to 

 day. 



PART III A BEE 

 PREPARATIONS FOR WORK 



Each pupil should be supplied with a living worker and drone bee. The glasses 

 used in mould -culture can be used for this purpose. The teacher should have one or 

 two " queens " at hand for comparison. Hand lenses may be used with advantage.
