flower buds are stuck, cup downwards, and ranged completely over it, and
there left from twelve to seventy-two hours.

Some houses, such as that of Messrs. Pilar and Sons; Pascal Brothers; H.
Herman, and a few others, have 3000 such frames at work during the
season; as they are filled, they are piled one over the other, the
flowers are changed so long as the plants continue to bloom, which now
and then exceeds two or three months.

For oils of the same plants, coarse linen cloths are imbued with the
finest olive oil or oil of ben, and stretched upon a frame made of iron;
on these the flowers are laid and suffered to remain a few days. This
operation is repeated several times, after which the cloths are
subjected to great pressure, to remove the now perfumed oil.

As we cannot give any general rule for working, without misleading the
reader, we prefer explaining the process required for each when we come
to speak of the individual flower or plant.




SECTION III.


Whenever a Still is named, or an article is said to be distilled or
"drawn," it must be understood to be done so by steam apparatus, as this
is the only mode which can be adopted for obtaining anything like a
delicate odor; the old plan of having the fire immediately under the
still, conveying an empyreumatic or burnt smell to the result, has
