The Experiment Successful — Notwithstanding protracted dry 

 weather a fairly satisfactory Mushroom exhibition was realized May 2'i 

 as per previous notice. About sixty species were shown, perhaps half 

 of them fresh ; many of these being edible kinds. With the numerous 

 class charts and colored plates used in the regular college work, an ex- 

 hibit was made that seemed to be very satisfactory to the large crowd of 

 visitors. Repetition when weather is not adverse may be expected.

Puff-Ball Family — The name for this group is Ly-co-pcr-da'-cc-ac ; 

 which is formed from Ly-co-pcr'-don, the name of one of the genera. 

 Pufif-balls are familiar objects, and numerous species are to be found in 

 every locality. They are edible when young and fresh, though only the 

 larger kinds would be used. Fig. 29 shows the Giant Puff-Ball grow- 

 ing in a grassy plot, from a photograph taken by Prof. Schaffner. The 

 myriads of spores escape as a cloud when the plant is ready to be stepped 

 on. When slicing the peeled specimen for table use the flesh should be 

 white; if dark or changing from the white color it must be discarded.
