probably more suitable for turnips, and at an elevation of 

 200 to 290 feet in one set of experiments (Thurston), and 

 at an increased elevation of 550 feet in the other (Wood- 

 hall), by which, of course, the climate was materially 

 changed. The results of another series of experiments, 

 carried on in Berwickshire for several successive seasons, 

 are more favourable to the mangold. These are best seen 

 in the tabulated form given by the experimenter. 1 



The reports of the crops last season throughout the 

 country, though irregular in many places, were, on the 

 whole, very satisfactory; 40 to 50 tons per acre were fre- 

 quently heard of; 2 while the Banbury Agricultural Society, 

 on inspecting the crops in their district, for the adjudi- 

 cation of their prizes, met with a field on the farm of 

 Col. North, of Wroxton Abbey, which gave a produce of 

 no less than 63 tons 11 cwts. to the acre. In Jersey, 

 where the soil and climate are naturally well suited to the 

 plant, we find, from the report of the Royal Jersey Agri. 

 Society (1857), that 70 tons of trimmed roots to the 

 acre were obtained at St. Peter's, upon a piece of common 

 grass land which had been broken up the previous autumn. 

 When the Regent's Park in London was formed, some

2 By the report of the Inspectors of the Manchester and Liverpool Agricul- 

 tural Society (1859), the crops of mangold to which the prizes were awarded 

 averaged respectively 51 tons, 46 tons, and 45 tons per acre.
