marked 7 floats in it, itis good; if not, itis poor. A good root gener- 
ally turns to a pink color when cut with a knife and exposed to the 
air; a poor root blackens. The pulp is an excellent fodder for dairy 
cows, if mixed with other food. A ton of pulp is equal to one and a half 
tons of beets. It isimportant to the success of the culture that the chemi- 
cai constituents drawn from the soil be returned in the form of manure. 
Mr. Caird, in the London Times, gives an account of the successful 
experiment in beet sugar manutacture by Mr. Duncan, at Lavenham. 
The year 1870 was the third year of the Lavenham factory and of the 
successful growth of the sugar-beet in- England on any considerable 
seale. It is now converting four hundred tons of roots per week into 
crystallized sugar. The chemical analyses of the roots in the previous 
years were satisfactory, but the chemical and mechanical processes for 
extracting the sugar were defective. Perseverance and intelligence 
have finally triumphed over difficulties, and the sugar industry is now 
successfully inaugurated in England. Mr. Duncan is satisfied that Sut- 
folk County is as well adapted to the beet culture as Northern France. 
The total value’ of the sirup produced in 1869 was £960. Expendi- 
‘tures of all kinds, including excise duties, amounted to £660, leaving a 
profit of £300, besides the pulp and the refuse products of manufacture. 
In 1870 the roots improved in their percentage of sugar; but, on the 
other hand, sugar is very cheap. The return of the pulp and refuse 
products to the soil prevents its impoverishment. The establishment 
gives employment to the entire surplus labor of the parish, at good 
wages, during the slack season. Capital is profitably employed, trade 
is stimulated, and the supply of sugar augmented. 
Mr. Campbell, of Buscot Park, Berkshire, is conducting a similar ex- 
perimental beet culture, to be devoted to the manufacture of sugar, or 
to the distillation of spirit, as may be most profitable. His crop has 
realized all his expectations, showing that Berkshire, as well as Suffolk 
County, is well adapted to the beet culture. The sugar-beet, even used 
solely as stock feed, is superior to the mangold, a ton of the former . 
being equal to a ton and a half of the latter, according to Dr. Voelcker’s 
analysis. 
Independent, then, of the sugar and spirit manufacture, the sugar-’ 
beet promises an extensive introduction into English agriculture. There 
are now about 200,600 acres of mangolds grown in the counties between 
the Marsh and the English Channel. One-fourth of this area devoted 
to sugar-beet will secure 60,000 tons of sugar per annum, about one- 
tenth of the present sugar consumption of the United Kingdom.

*The region of country lying west of the Missouri River, between the 
parallels of 35° and 45° north latitude, and known as the high plain re- 
gion of the United States, extends to and embraces the eastern water 
shed of the Rocky Mountains between those parallels, including the 
States and Territories of Nebraska, Kansas, Colorado, New Mexico, and 
the Indian Territory. in consequence of the rapid settlement of this 
extensive tract, occasioned by the facilities which the several new rail- 
road lines afford the emigrant for reaching this heretofore almost inac- 
cessible domain with supplies and implements of husbandry, it has be-
