ANNUAL REPORT OF NEW-YORK 



mination in this respect was necessary, and was, indeed, an indis- 

 pensable step in the process of analyses. The same may be said 

 with regard to the mineral matter or ash. 



" Under the foregoing heads we have acquired it is hoped a very 

 important amount of information — such, too, that it can be imme- 

 diately brought to bear upon the practical nutritive values of the 

 different grasses. 



^' The grasses, sixty or seventy specimens, each individual plant 

 composing the sample of 2 or 3 lbs. w^eight were taken from mead- 

 ows in which they were growing naturally and healthy. The 

 grasses were collected, plant by plant, at the time of flowering 

 (except when otherwise stated.) 



" To economize space and aiford facilities for comparison, the 

 analyses are collected in tables. I shall divide them into two 

 classes, which for convenience sake, may be called the natural and 

 artificial grasses, respectively. 



" The tables I. and II. contain the botanical and common names 

 of each grass, the nature of the soil, and the date of the collec- 

 tion of the different specimens :
