136 PICTURING MIRACLES 



a bit as the sporangia, little round balls, formed on 

 the end of each filament. I could see and picture the 

 circulation in the filament, the forming of the spores 

 in the sporangia, while it was still growing; soon it 

 turned dark, then black, and finally split open and 

 discharged the sporesthousands of them from each 

 tiny spherical ball. The circulation of the protoplasm 

 was as regular and as easy to see as in a pollen tube. 

 It was a steady flow back and forth in channels in 

 the filament which was about one-hundredth of an 

 inch in diameter. In the young, semitranslucent 

 sporangia, it seemed to be moving in all directions 

 as though it was boiling. This movement was visible 

 only a short time, as it soon turned black and became 

 opaque, hiding the actual forming of the spores. 



While I was doing this work I was always looking 

 for a zygospore but without success, when I found 

 out that to get zygospores I must have the mold 

 plants capable of producing them. This mold plant 

 is really a very wonderful thing. It has two methods 

 of reproduction through the spores and the zygo- 

 spores. Any form of bread mold will produce spo- 

 rangium and it reproduces through the spores, but in 

 order to get zygospores, I must have what you might 

 call male and female plants, although that definition 

 is not true because either is male or female, so it is 

 designated as plus and minus strands in the plant.
