= pollinia. Passing to a new flower (or another part of the same per- 
haps) the same Ait ess is renewed, and I have found strings of the 
glands and shafts thus attached to each other, particularly on the old 
flowers of A. incarnata. On one occasion I caught an insect, on A. incar- 
nata I believe, which had drawn out the pollen of this species by means 
of the shaft of A. purpurescens. At that time I had not a set of the va- 
there any rule in the matter? My lamented friend, W. W. Denslow, was 
piads - ep when death cut short his studies. I had urged him to 
Write to you the subject but he had points which he wished first to

about noon, a kingfisher perched on a tree, making his u wild notes, 
and looking for his game; below him was a small petite a ans which 
_ does not freeze over in the coldest weather and in which fish can be seen. 
The day mentioned was ve cold, 20° below zero. I had supposed that 
those birds went to the South long before this. Can they endure our 
wein cold weather? Where do mod ges: — in our very cold

of innumerable acari eRe — on his potatoes. In less than 
eight days these little arachn so abundant as entirely to
