The curl, aſſerted to be owing to forcing thie plants from which the ſets are taken by manure or earthing(7). Southern aſpecét and rich land, bad. Do not curl on the mountains of Radnor and Montgomery(e).

Curl, owing to earthing(5), and from chufing the largeſt roots for ſets that were made large by earthing and hoeing(7/j4. Frefh dung greatly detri- mental, and will cauſe the curl ſ&ε.

In Vorkfhire, the moor-lands are at preſent in a manner free from it, while the vale is ſtill infeſted ¶◻l.

It is a queſtion, whether the curl is not owing to being heated when kept, during winter, in the houſe; as when kept in pits, under ground, fewer of them are liable to that diſtemper(m).

OBSERVATION.

The circumſtance of moſs or peat-earth being a preventative of the curl,

is very curious, and much deſerves further enquiry. The experiments

hitherto made, do not ſeem ſufficiently extended and accurate to admit of any certain conclufions.

ACCIDENTS. Raoxks.

Mr. Billingfley. Be particularly attentive to the rooks; who, by ſaga- city of ſmell, find them out, and make great depredation(n).
