(2) Take a little piece of the mould, and put it in a drop of water 

 on a little slip of glass ; hold it up between your eye and the light, 

 and choose a transparent part at the edge. 



Record and draw as before what you see. 



(3) Choose a piece from a more shabby-looking patch, and repeat 

 the operation. 



(4) Take some of the greenish dust from the mouldy lemon and 

 scatter it on the surface of a dish which has been covered with gelatine. 



SUGGESTIONS FOR FURTHER WORK OUT OF DOORS 

 See how many different moulds you can find upon various dead 

 or living plants, and sketch them as you can see them with the 

 naked eye. When you have begun more advanced work in natural 

 history, you will find that the examination of moulds with the 

 microscope is of considerable interest. 



PART III A MUSHROOM 

 PREPARATIONS FOR WORK 



Each student should have a newly expanded mushroom. Some deep seed-pans 



containing growing mushrooms and living 

 spawn which have been specially prepared 

 and kept until wanted plunged in a mush- 

 room bed as indicated below, should also 

 be provided. 



Fresh horse manure should be obtained 

 seven weeks or so before the mush- 

 rooms are required sufficient to make up 

 a bed not less than a yard square and 

 Irom nine inches to a foot in thickness. 

 This should be kept under cover, and if 

 too dry should be watered once. The ma- 

 terial is damp enough, if, when squeezed 

 it will bind together without the exudation 



of any moisture. The longer pieces of straw
