and one of the Conductors of this Magazine. 
Tub Dahlia is certainly one of the most splendid plants in creation ;— 
for whether the brilliancy and variety of colours in the flowers, the 
extent of its varieties, the duration of its blooming, or its majestic ap¬ 
pearance when in perfection, be considered, it stands in each particular 
unrivalled, and merits a situation in every garden, from the palace to

The best mode of treatment practised with the Dahlia, has repeatedly 
been requested through the medium of publications; and although I am 
not vain enough to think the method I pursue is the best in operation, 
yet, having been so successful as to flower the plants to the satisfaction 
of hundreds of persons who have viewed them, I venture, in a plaia and 
brief manner, to give a detail of my practice; in doing which, I shall 
state the mode I have adopted in raising a number of handsome seedlings, 
as well as the subsequent culture. 
New varieties are raised from seed, and with a view to raise the best 
and particular kinds, I have recourse to artificial impregnation. With a 
small pointed camel’s-hair pencil, I take the farina from one flower to 
another. If I have a handsome compact flower, that I am desirous of 
Improving in colour or size, I have recourse for farina from one of the 
colour or form I desire ; as it is very nearly to be calculated what a mix¬

pand. When the first and second tier of florets are expanded, I then
