from on« section of our country to another, and thereby spread mor« 

 extensively the more useful and profitable class of grasses. 



This subject of grasses is a voluminous one ; more ha^been aaid

 has been estimated at 168 pounds per year. It has been ascer- 

 tained by experiment that lUU parts of cream contains 4^ of butter, 

 and 3^ of curd. We have the authority of Dr. Brande, for saying 

 that butter will not keep good unle-s the adhering curd is thoroughly 

 separated from it. This may be done by carefully melting it by the 

 heat of a water balh, at l"ii..° Fahrenheit, rnl continuing it in a 

 liquid state some time, so as to eiTect a complete purification ; the 

 liquid butter should be decanted, strained and salted, and if put in 

 small jars clrsely covered, it may be kept for a long time nearly 

 fresh. Cleansing butter from the cLrd can be very effectively done 

 by thoroughly washing and working it "n cold water. The latter pro- 

 cess is generally preferred, because of the injurious effect en the
