ately to the laboratory, and the amount of moisture contained in it 
was determined without loss of time. Dried at 100° C., the green 
grass lost 65.97% of its weight.* This grass contained 1.35% of ash. 
3. Bog hay (Carex stricta?) from Mr. J. Hathaway, Rochester, 
Mass., mown August, 1874. No seeds nor flowers could be detected 
in the sample. Many of the stalks or leaves were dead, or nearly so. 
4, Bog hay (Carex stricta?) from Mr. Joseph Church, Rochester, 
‘  Mass., crop of 1874. Some of the stalks or leaves in the original 
sample were dead; but as many as possible of these dead stalks were 
thrown out from the portion taken for analysis. 
5. A sample of dead and weather-beaten sedge (Carex stricta?) 
gathered by hand, December 26, 1874, in a meadow upon the farm of 
Mr. D. Lewis, Rochester, Mass. 
The result of these analyses will appear from the following tables : —

* Mr. John Welles, of Dorchester, reported in the “‘ Massachusetts A gricultu- 
ral Repository ” for the year 1823, 7. 311, and for 1825, 8 pp. 74, 76, that he 
had found in 1822 that 100 Ibs. of green ‘‘ fresh-meadow grass” gave 38 Ibs. of 
hay, and in 1823 that 100 lbs. of fresh meadow-grass, cut July 23, gave 44 Ibs. 
of hay. 
In one of the upland sedges (Carex muricata), gathered when in blossom, 
Sprengel (Erdmann’s “ Journal tech. und ek. Chemie,” 1830, 9. 12) found 60% of 
water, and 4.07% of ash (= 10.17% of the anhydrous hay). 
Witting (“Journal praktische Chemie, 1856, 69. 153) found in fresh plants 
of Carex remota 52.75% of water (on drying at 100°) and 2.07% of ash; in 
Carex acuta, 69.60% of water and 1.12% of ash; and in Juneus communis, 62.00% 
of water and 1.42% of ash. Detailed analyses of the ashes of these plants have 
been given by Witting in the cited memoir. 
t An estimation of moisture made June 24, 1873, 7.e., ten days after the 
sedge was gathered, gave 7.96% (dried at 100° C.). A determination of crude 
ash made at the same time indicated 6.66%, calculated on the air-dried hay.
