ticularly during the night; but seed ripens best in the open air, and 
when under glass but few seeds set, and still fewer are properly ripened. 
I do not think it advisable, however, to take the Rnodanthe out of the 
pot and plant it in the open ground, as it cannot well be protected from 
heavy rains and the burning sun, which is absolutely necessary with all 
tender plants.

ON FLOWER POTS. 
BY THE EDITOR. 
In giving directions for the treatment of the different kinds of green¬ 
house plants, it is frequently necessary to mention flower-pots of different 
sizes; and several of my readers have written to ask me the dimensions 
of the pots which gardeners in the neighbourhood of London call sixties, &c. 
To explain this, it must be understood that the potters take a certain 
quantity of clay, which they call a cast, and that the pots are numbered 
according to the number made of them from one cast. Potters always 
charge the same price for a cast, whether it consists of two pots or of 
eighty. 
There are several different kinds of pots which are not included in the 
ordinary numbers; but of the common flower-pot, which, as my readers 
probably know, is a cylindrical, tapering vessel of burnt clay, with a 
perforated bottom, there are eleven common sorts, distinguished by 
their sizes, thus : the first size has two pots to the cast, which are called 
twos, and which are eighteen inches in diameter and twelve inches deep ; 
the second size has four to the cast, which are called fours, being twelve 
inches in diameter and ten inches deep; the third size has six to the cast, 
which are called sixes, being nine inches in diameter and eight inches 
deep ; the fourth size has eight to the cast, which are called eights, being 
eight inches in diameter and seven inches deep ; the fifth size has twelve 
to the cast, which are called twelves, being seven inches in diameter and 
six inches deep; the sixth size has sixteen to the cast, which are called 
sixteens, being six inches in diameter and seven inches deep ; the seventh 
size has twenty-four to the cast, which are called twenty-fours, being five 
inches in diameter and six inches deep ; the eighth size has thirty-two to 
the cast, which are called thirty-twos, being four inches in diameter and 
five inches deep; the ninth size has forty-eight to the cast, wdiich are 
called forty-eights, being three inches in diameter and four inches deep ; 
the tenth size has sixty to the cast, which are called sixties, being two 
inches in diameter and two and a half inches deep ; the eleventh size has
