a key to the proper system of manuring to ensure a paying 
crop. The ashes of the fully-developed turnip-bulb consist 
for the. most part of potash, soda, lime, phosphoric-acid, 
sulphuric-acid, and common salt. In a ton of turnips there 
are about 7\ lbs. of potash, 1 J lbs. of soda, 6 lbs. of lime, f lbs. 
of magnesia, 2^ lbs. of phosphoric acid, 3^ lbs. of sulphuric 
acid, 5 lbs. of common table salt, or chloride of sodium. 
Now, if the bulbs abstract these substances from the soil, the 
system of manuring must be such as to restore them, or such . 
of them,, at least, as the soil is naturally deficient of. For a 
sandy soil kainit and superposphate will be suitable refreshers; 
guano and phospho-guano will suit any old garden soil ; and 
good fat stable manure will answer in the very best manner to 
prepare any soil for turnips, whether loam, clay, or sand. 
Selection of Sorts. — As to sorts there is not much choice, 
and nobody goes mad about turnips, as they do about peas 
and potatoes. A few have been already mentioned, but here 
is a list of such as we consider sufficient, having tried again 
and again ad nauseam in the experimental garden at Stoke 
Newington all the sorts we couid obtain by worrying the 
trade and scouring the country. 
Turnips eor Early Sowing.— Early White Butch , , Six 
Weeks, Early Snowball. 
For Succession. — Red American stands well after the 
growth is finished ; Yellow Malta. 
For Main Crop .—Red American, Six Weeks, VeitcKs 
Red Globe. 
For Late Sowing to stand the Winter. — Orange Jelly , 
Jersey Navet, Chirk Castle. 
Where turnips are grown in any quantity it is of the 
utmost importance to shift them about from place to place, 
so as to put them on soil that has not seen turnips for a year 
or two, in other words, to observe the first principles of 
“rotation.”
