which is unreported. A great deal of this is
of inferior quality and produced from half-wild bushes. The 1919
figures are: area, 48,843 _cho_; number of factories, 1,122,164; green
tea--_sencha_, 7,205,886 _kwan_; _bancha_, 2,580,035 _kwan; gyokuro_,
75,826 _kwan_; black, 50,756 _kwan_; others, 234,868 _kwan_; _sencha_
dust, 249,862 _kwan_; other dust, 486 _kwan_. Total, 10,397,719
_kwan_; value, 33,377,460 yen. There was exported green tea (pan
fired), 12,420,000 yen; green tea (basket fired), 4,575,000 yen;
others, 1,405,000 yen. Of this there went to the United States
consignments to the value of 15,600,000 yen and to Canada of 1,700,000
yen. In 1918 the export to America was 50,000 tons; in 1919, 30,000;
and in 1920, 23,000; and a further decline is expected in 1921. The
total exports, which were, in 1909, 62 per cent, of the production,
were, in 1918, only 57 per cent, and, in 1919, 37 per cent.

THEINE PERCENTAGES.--The following percentages of theine in black and
green tea were furnished me by the Department of Agriculture:

---------------------------------------------------
|Green |Green |Black |Oolong
|(Basket Fired) |(Pan Fired) | |
---------------------------------------------------
Theine |2.81 |2.22 |2.26 |2.35
Tannin |15.08 |14.29 |7.32 |16.15
---------------------------------------------------

Theine or caffeine is a feathery-looking substance which resembles
the material of a silk-worm's cocoon. There is more theine or caffeine
in tea leaves than in coffee.

MISTAKES IN CROP STATISTICS [LVIII]. Generally speaking, it may be
said that cereals are under-estimated and cocoons over-estimated.
Cereals may be 20 per cent. under-estimated. The under-estimation may
no doubt be traced back to the time when taxation was on the basis of
the grain yield.

OCCUPATIONS FOR THE BLIND [LIX]. A third of the 70,000 sightless are
_amma_, about a quarter as many practise acupuncture and the
application of the moxa, while nearly the same number are musicians or
storytellers. The blind have petitioned the Diet to restrict the
calling of _amma_ to men and women who have lost their sight.

WELL SINKING FOR GAS [LX]. The presence of gas, which is odourless, is
betrayed by the discoloration of the water from which it emanates and
by bubbles.

HEALTH, HEIGHTS AND WEIGHTS OF SCHOOL CHILDREN [LXI]. In 1917-18 the
