GARDENING FOR THE SOUTH. 



Knight's Tall Marroic. — Grows about six feet high; 

 bears a long time and abundantly, and is of first-rate ex- 

 cellence ; later than the above. 



New Mammoth. — A pea of the same height, and of equal 

 excellence with the foregoing ; comes into use about the 

 same season ; productive. 



If the above are not to be had, Early Frame, Early 

 Charlton, Early Grotto, Dwarf Blue Imperial, Blue Mar- 

 row, Banksian Marrow, Blue Prussian, Knight's Dwarf 

 Marrow, and Woodford's Prolific, are among the best re- 

 maining sorts. 



The best three varieties for a succession are Prince 

 Albert, Oedo-Nulli, and Champion of England. If con- 

 fined to two, I should reject the Prince Albert, though the 

 earliest of the three.

Potash and phosphoric acid are large constituents of the 

 ash of the pea. Ashes and bone-dust, or superphosphate 

 of lime, especially the former, are likely to be the special 

 manures most needed.
