Manure for Mangold iVurzel. 



crop, I hope it may be found to contain some useful hints to 

 mangold growers as to the best mixtures of manure for that crop. 

 Langley Park, Nov. 22, 1866. 



Sir, — The enclosed experiments were carefully conducted ; 

 the dung was drawn and spread under my eye ; the artificials 

 sown with my own hand ; the roots were pulled and weighed in 

 my presence : in short they have received my best attention.
