The Size of Garden Pots at Liverpool, hy Mr. James Rollins, of 

 Dingle Bank. — As the sizes of our pots here differ from those 

 used about London, I have annexed a sketch {Jig. 1 24.) of their 



numbers and dimensions. This may be useful ; and I could 

 wish some of your country correspondents would favour your 

 readers with a corresponding scale of the sizes used about the 

 metropolis. These pots are numbered 1 to 36 ; each pot is 

 exactly the same width at top and bottom, or, if any difference, 

 the bottom is rather narrower. The height, also, of each pot 

 is the same as the width. The same piece of clay which will 

 make the pot No. 1., will make 24 of the size No. 24.; and 36 

 of the size No. 36. ; and so on. Hence the origin of the potter's 

 expression of so many to the cast or dozen. 



is 20 in. in height and diameter, and 1 to the cast.

Nitre. — I watered a bed of choice carnations last season 

 with a weak solution of nitre, repeating it occasionally. Its 

 good effects were unequivocally manifested in the luxuriance 

 of the leaf and size of the flower.
