but at first the milk acquires somewhat of a bitterish taste. This 
kind of green food is also accounted excellent for promoting the 
production of butter. At the approach of winter, the roots of the 
succory plants are dug up and stored in a cellar or out-house. 
They are laid horizontally in a bed composed of sand or light soil, 
with the crowns or heads outermost and uncovered ; a thin layer 
of* soil is then added ; then another row of roots ; and this is re- 
peated till the beds be perhaps three or four feet high. It is 
only necessary that the place in which the roots are thus stored 
be defended from frost ; light is not only unnecessary, but 
would be prejudicial. Here they afford the blanched shoots cal- 
led j Barbe-de-Capucin, much relished in France as a winter 
salad. Frequently the roots are packed among moist sand in a 
barrel, having numerous round holes pierced in its sides : the 
crowns of the succory plants are so placed, that the shoots may 
readily push their way through the holes : they are thus kept 
quite clean, are very easily gathered as wanted, and repeated 
cuttings are obtained. Barrels thus prepared are sometimes 
carried on board vessels about to sail on long voyages, and fresh 
salads are thus procured after the ship has been some months 
at sea. When sent to the Paris market, the succory roots are 
generally drawn from the beds, and tied in bunches, with the 
etiolated shoots attached to them. — Hort. Tour , p. 368. 
01. Ringing of Walnut-trees — The Baron de Tschoudi, 
near Metz, in Lorraine, has introduced the practice of ringing 
his walnut-trees ; taking out two inches of the outer bark all 
all around, and plastering over the part with the 44 onguent de 
St Fiacre,” i. e. clay mixed with cow-house cleanings. The 
ringed walnut-trees not only prove more prolific, but the fruit 
is more early. — Hort. Tour , p. 489. 
32. Ailanthus glandulosa. — This Japan tree has become a 
common ornament of gardens at Paris, while in England it is 
rather neglected. It seems admirably well adapted for plant- 
ing on the margins of public promenades, as it flourishes in the 
poorest and most arid soil, sending its spreading roots abroad 
in search of moisture and nourishment. In the hard gravel- 
walks of the Jardin des Plantes, it remained quite green, after 
the parching heat and drought of July and August ; while the 
lime-trees (rows of which extend the whole length of the gar-
