of sugar, and some 8 per cent of protein, more than 75 
per cent of the total weight is digestible. Unusual- 
ly large trees may reach a height of 60 feet with a 
crown 75 feet in diameter, and may produce as high as 
3,000 pounds of pods. These pods are a concentrated 
feed for horses, milch cows, and fattening stock; to 
a certain extent they replace oats for horse feed.. 
Sirups and various sweetmeats are sometimes prepared 
from the carob pods; they are relished by most children 
and are sometimes of f ered f or sale by fruit dealers in 
America. (Adapted from description by Mr. W. T. Swingle,)

It has never done well in Florida but thrives in 
Southern California." (Falrchlld.) See Inventory 35,

Citrus ichangensis (Rutaceae), 45931. Lemon. From 
China. Collected by Mr. Frank N. Meyer, Agricultural 
Explorer for this Department. "(No. 1288. Changyang, 
Hupeh, China. December 10, 1917.) A large variety of 
Ichang lemon, mostly shipped down to Shansi, a few 
days run down the river. The fruits sell wholesale 
at 1 cent (Mex. ) a piece and retail at 2 to 3 cents 
(Mex.) according to size and supply. The Chinese, 
with their great dislike to sour fruits, never use 
these lemons in beverages but employ them only as room 
perfumers or carry them about to take an occasional 
smell at them, especially when passing malodorous 
places. Locally the rind is candied in a limited way 
and resembles orange peel in flavor and appearance. 
The fruits ripen during the month of October; and, 
since they do not possess long keeping qualities, they 
disappear very quickly. In fruit stores, in Ichang 
they are all gone by mid-December. The trees grow 
to medium-large size and resemble pomeloes in general 
appearance though they are less massive In outline 
and the foliage is of a lighter hue of green. The 
trees are densely branched and have large spines on 
the main branches and small ones even on the bearing 
branchlets. The foliage suffers a good deal from 
caterpillars; the trunks are attacked by borers, and 
maggots are occasionally found in the fruit. Foreign 
residents in and around Ichang make from these lemons 
a very fine lemonade which is of a more refreshing 
quality than the ordinary kind; they are also used in 
pastry, sauces, and preserves. On the whole it seems 
that this Ichang lemon is a very desirable home fruit 
for those sections of the United States that, are
