water as fast as it evaporates. Probably a great many 

 sprouts will start at once, or in quick succession ; break 

 off all but three or four of these, as the Tine will, by so 

 doing, be much longer and more luxuriant. Nothing 

 now will be needed for the well-being of the vine, except 

 to keep the vessel filled with rain-water.

 ADAPTATION TO LOCALITIES. 



The Sweet Potato is not only at home in all the 

 Southern States, but is produced in large quantities in 

 Central New Jersey, Delaware, and Central Illinois, lat- 

 itude forty degrees ; it has also been successfully raised in 

 gardens in nearly the coldest parts of the State of New 

 York, as well as in Maine, Southern Minnesota, at St. 

 Paul, which is in latitude fcrty-f ou^ to forty-five degrees. 

 It is probable that, tinder nortberr cultivation, varieties 

 may originate especially adapted to cold climates, so 

 that, were it needful, it© profitable cultivation might 

 be extended several degrees of latitude northward, as is 

 said to have happened in Europe with regard to maize, 

 for which it is asserted that forty-six degrees north lati- 

 tude, was formerly the limit, whereas now it is cultivated 

 nearly to fifty-two degrees. 



"With a climate and soil such as tide-water Virginia, 

 and other maritime sections, possess, there is no reason 

 why every family should not be abundantly supplied with 

 these nutritious tubers, and should also furnish for mar- 

 ket, to a large extent, all less favored sections.
