Investigations into the cause Of dis IN

and applestrees by; Prof. Z. j.. Burrill, 4.
His paper in the July Americdn Ndtu
roliSt opens up a prospect that blightin n4t
fruit trees can be combated successfully ~.
by careful tests of the diseased parts and
the use of a knife. He found the starchy.
particles in the bark Of diseased pear
trees full Of bacteria, and succeeded in
inoculating healthy from diseased trees. t.,.
While cutting away infected parts the
greatest care has to be etaken lest healthy f
tissue become inoculated by the knife. Eg1s
The yellows of the peach tree are of the Hrt
same nature, and the Lombardy poplar
and aspen suffer from asiInilar disease. u
