II. A specimen of blue joint-grass gathered July 7, 1876, upon the 
D. Lewis farm at Rochester, Mass., by my assistant Mr. D. S. Lewis. 
The stalks were of uniform length, four feet, and the plants were in 
blossom. The meadow from which this sample was collected was very 
dry, no rain having fallen in the vicinity for six weeks or more. The 
specimen was dried in the shade and analyzed as hay. No attempt was 
made in this case to determine the amount of moisture in the green grass, 
since it was collected at a distance from the laboratory. 
III. Reed Canary-Grass (Phalaris arundinacea) gathered June 13, 
1876, on the banks of Stony Brook, near Boylston Station, on the Boston 
and Providence Railroad, from low ground that was shaded a considerable 
part of the day, perhaps a quarter of the day. ‘The sample was not par- 
ticularly uniform as to the size of the stalks, some of them being 44 feet 
long with buds fully developed, though no blossoms; while other stalks 
were not more than two feet long with buds just appearing. The sample 
was covered with dew when gathered, and the estimation of moisture 
(74.699), as recorded below, relates to plants from which the dew had 
just dried off. The larger part of the sample was made into hay in a 
shady place and analyzed as such. 
IV. Reed Canary-Grass (Phalaris arundinacea) gathered June 15, 
1876, from the edge of a running brook on the Bussey Farm, nearly two 
miles distant from the locality where No. III. was collected. The stalks 
were of uniform length, 3} feet, and the buds upon them were fully de- 
veloped, but not yet opened. . The specimen was dried in the air in a 
shady place, for analysis. An estimation of moisture in the grass, as 
gathered, gave 78.83%.

The close agreement of these analyses of samples collected from 
very different localities is to be noted, as well as the fact that the
