flowers while still growing, I was surprised to find this 
cavity filled with flies somewhat larger than the common 
house-fly, all busy as could be in eating the pollen, of 
which scarcely a grain then remained. I counted four-

The delicate little rock-rose sheds its petals so quickly 
that we can hardly see the use of its opening them, 
while its neighbor in the list, the dog lily, is persistent 
in retaining its petals as long as possible. The little 
evening primrose now opens its quiet eye, and is liable
