study of the question, in which he says the cultivation of the Cinchona promises com¬ 
plete success, and will prove remunerative, if attention be paid to selection of species, 
and the cultivation be properly conducted, and that Mr. M‘Ivor’s plan of mossing is 
an important discovery in the direction of intelligent culture. 
We have said enough, we trust, to show how interesting this book is, and Mr. Howard 
deserves the best thanks of the world, not for the present publication only, but for his 
long and patient study of the subject in all its bearings,—studies which place him in 
tire front rank among living quinologists, and renders his opinion on all questions 
connected with the subject of the greatest value and importance.

We have received some numbers of this publication, and are well pleased to find the 
name of an old friend among those of the contributors to its pages. Dr. J. B. Edwards, 
formerly of Liverpool, but now of Montreal, is not only chairman of the committee of 
publication, but appears to be one of the principal writers for its pages. We congratu¬ 
late him on having found in the New World so congenial a field for the exercise of his 
literary talent. 
BRICK TEA. 
From an interesting paper in the ‘ Food Journal’ for March, on the economic uses of 
brick tea, we glean the following facts :— 
The manufacture of brick tea appears to have been in the hands of the Chinese until 
within the last nine years, but it is now made to a large extent by the Russian agents 
at Kiachta. It takes three forms, “ large green,” “ small green,” and “ black bricks,” 
and is made from the coarser leaves and upper twigs, to which are added much of the 
broken leaf and dust resulting from green-tea manipulation. The mass is simply moist¬ 
ened by the application of steam, then compressed in wooden moulds, having the “chop ” 
of the manufacturer cut in relief on one of the inner surfaces. The bricks are then piled 
up in stacks protected from the sun and rain, but having a free current of air circulating 
through and around them. When quite dry, each brick is enveloped in paper, 36 bricks, 
built into an oblong figure, are covered with dry fragrant leaves, and the whole matted 
over; such packages are known as “ baskets.” This form of tea is of a dusky green 
colour. The Mongol buyer tests the soundness of his purchase by placing a brick upon 
his head and pulling the extremities downwards with both hands; should it neither 
yield nor break, it is considered sound. Occasionally a similar test is applied over the 
bended knee. 
In Mongolia and Tartary the method of preparing brick tea for drinking is as follows: 
—The leaves are rubbed to fine powder, boiled with alkaline steppe-water, to which 
salt and fat have been added, the decoction being carefully decanted. Of this liquid the 
nomadic races drink from twenty to forty cups per day, mixing it first with milk, butter, 
and a little roasted meal, upon which they are said to maintain perfect health.
