cording to recent statistics, the areas
devoted TO small fruit culture there. in

ages from S1s, 900, 900 to $40. 600, 900. The
industry has beer a veritable boon to
English agriculturists. Small fruit
growing is taking the place Of unprofit-
able roo and grain crops. In the coun-
ty OF Kent alone there are about So
900 persons engaged as growers, pickers

WOOD brought TO a mirror polish is
coming into use for ornamental pur-
poses in Germany, and has this advan-
tage, that, unlike metal, it Is not af-
fected by moisture. The stuff is first
treated with a bath Of caustic alkali for
W or throe days, at q temperature be-
tween 1854 degrees and 1917 degrees f.
Next comes n dip in hydrosulphate Of
caloium, for from twenty-four to thirty
six hours, after which a concentrated
solution OF sulphur Is added. After
another soak in an acetate OF lead solu-
ton, at 95 degrees to 100 degrees F., it
is thoroughly dried and polished with
lead, tin or zinc, as may be desired,
when it resembles shining metal.-Sci-
