not by any means be taken into a house of any sort, as if more 
than six inches from the glass they become attenuated, and also 
they require a constantly moist regular heat of about 65 , and 
nothing suits them so well as to stand upon some description of 
fermenting material, in which situation they should continue till

have attained their full growth, and bear an abundant bloom, 
when they may be taken to the greenhouse. 
It must be understood that water is to be supplied to them 
liberally during the whole period of their growth and blooming;

THE CULTURE OF TROPiEOLUM TRICOLORUM. 
Sir,—I offer you the following remarks on the cultivation of 
those beautiful climbers, Tropaeolum tricolorum and brachyceras, 
not as an infallible and never-to-be-departed-from rule,but simply 
as a detail of my manner of growing them; but as I have hitherto 
obtained vigorously grown plants and an abundant bloom, I 
feel some confidence as to the results, and am not without a 
hope of its proving useful to the amateur, more especially your 
correspondent on whose behalf you request me to write. There 
are two things indispensably necessary to the successful cul¬ 
ture of these plants : they are, good soil, and a good situation 
in which to grow them. It is very common for a writer, in de¬ 
scribing a subject similar to the present, to say the plants le- 
quire peat, or peat and loam, as the case may be ; and peihaps 
it may be sometimes necessary to be thus brief, but here the 
amateur grower is often at a great loss, for these eaiths differ 
as much as any manufactured fabric ; yet on the proper selec¬ 
tion of them his greatest chance of success depends. Peat, in 
the common acceptation of the word, varies from the free, rich
