230 AGRICULTURE ON THE PACIFIC SLOPE 



Until recently there has been a great deal of loss every 

 year from this cause. Now we have found out how to 

 prevent it. 



If you wish to see how this is done, place a very 

 moldy orange or lemon in a cup and cover it with water.

You will then probably see on the top of the water some- 

 thing which looks like dust; this is made up of very 

 fine particles, each one of which is a spore. Each one 

 of these spores will grow and make a mold spot if it 

 gets a chance. 



Take a souncUemon or small orange and mark it with 

 some sort of design (such as a cross or your initials)
