in France, is that of M. Laurent, near Paris. He 
had when I visited his establishment some years ago 
three or four acres entirely covered with low span- 
roof and lean-to houses and_ pits, specially for 
forcing Roses and Lilacs, these being the only two 
plants he cultivated. Iam quite afraid to say the 
number of Roses which are here forced annually, 
but I should judge there could not have been much 
less than twenty or thirty thousand. 
It was early in February when I saw them, when 
the houses and pits were all full, and many 
thousand plants outside ready to take the place of 
the early forced Roses, as soon as their blooms were 
over. The blooms are gathered every morning, and 
sent to Paris for bouquets and decoration, for which 
there is always a large demand. The plants from 
this establishment are not sold. M. Laurent is also 
celebrated for forcing Lilacs. His method of 
producing white flowers from the purple Lilac is not 
generally known or practised, nor am I thoroughly 
in the secret, but it 1s nevertheless a fact that he 
depends entirely upon the purple Lilac to produce 
the finest white blooms throughout the winter.
