work of Acidium Ranunculi. Viola pubescens gives Hcidium Viole, and 
later Puccinia Viole. Tramping on, Mertensia Virginica stops me by the yel- 
lowish spots on the leaves; I examine with my lens, and doubt its being a fun- 
gus, but throw a leaf dito my box. A microscopical examination at home 
shows it to be Aa! canescens, new to the United States—and then I wish 
I had been less skeptica 
Crossing the oi I add Puccinia Cryptotenee on C. Canadensis, and 
climbing up a deep gully, I am delighted with the eee of a large Lonicera 
Sullivantii, every leaf spotted by Acidium Periclymeni. Coming out, I find 
small shrubs of Zanthoxylum Americanum, aden and petioles bright with 
idium Zanthoxyli. A visit to the bogs adds Peronospora obducens on coty- 
ledons of Impatiens, ~ later in the season, Puccinia speta on Mitella di- 
phylla.’ During the season this valley yields several species of Peronospora, 
Entyloma, Septoria, Cercinor and many of the Erysiphei. 
w localities are as rich in species as this, but something can be found 
almost avin I have found heavy woods the most barren. River bottoms, 
low meadows, deep ravines, hills with springs running down them, and especi- 
ally recent Petes in the woods, are good collecting grounds. Sloughs and 
Swamps give the species on Sedges, “ae oe etc., and the grasses of dry 
rocky hills are usually covered with Puc

leaves carefully between sheets of paper, a drier between each, and when all 
are arranged, place a board on top, with a small weight, just enough to‘kéep 
the leaves well flattened; too much will injure cidia. It is necessary to 
change the driers often to make good specimens. When dry I poison them with

MARINE A1G.©.—The flora of the sea is distributed through a belt nearly 
touching the high tide mark on the one side and extending to a depth of sev- 
without difficulty at low tide, taken from the rocks by the hand or with the aid 
of some simple tool. For getting plants which grow just below tide, a pair of 
rubber wading boots, which will allow one to go into the water up to the 
knee or above, is very convenient. And for capturing plants which come float- 
ing up on the waves or are attached to the rocks just out of reach of the hand, 
Various things out of boiling water, in the process of cooking. This can be

two lower joints of a common fishing rod. These may be quickly taken apart
