1892.— The same rows of stocks were employed this season as 
had been treated the previous season, as many as possible of them 
having been budded as described subsequently on page 669. Those 
not budable were left standing for further treatment with fungi- 
cides. The treatments were as described on pp. 670, 671. 
Owing to the inferior character of the stocks originally 
planted this whole block would be considered worthless, as not 
one-half the stocks were budable in 1891. The effect of the Bor- 
deaux mixture, however, was plainly observable and a rough esti- 
mate made October 19 of the percentage of foliage still upon 
the unbudded stocks showing the Bordeaux to be much superior 
to the ammoniacal solution, and six treatments superior to five. 
Quince Lear-siicur (Hntomosporiwm macalatum, Levy.) 
Much that was said in reference to pear leaf-blight applies 
equally well to quince leaf-blight, which is caused by the attacks 
of the same fungus. The parasite, so far as the author’s observa- 
tion goes, never attacks the bark on the young shoots but is 
confined wholly to the foliage. The Angers quince seems more 
susceptible than the Orange and it is rare to observe after the 
first week in September a block of quince cuttings from which at 
least fifty per cent of the leaves have not fallen. Unlike the disease 
on the pear, the quince leaf-blight often seriously defoliates bearing 
trees in this section and commonly causes the fruit-grower much 
loss from its attacks on the ripening fruits, in which form it is 
called “fruit spot.”* | 
The experiments in the prevention of this disease were confined 
to one row of Angers quince cuttings, treated partly with Bor- 
deaux mixture and partly with ammoniacal solution.§§

1891.— One row of 509 cuttings was planted and treated with — 
fungicides in a manner described on pp. 668, 671. The season being 
an unusually dry one, no disease of any consequence appeared, and
