1S92 .—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 p. 261. Those not budable 
were left standing for further treatment with fungicides. The treat¬ 
ments were as described on pp. 262-263. Owing to the inferior char¬ 
acter of the stocks originally planted this whole block would be consid¬ 
ered worthless, as not one-half the stocks were budable in 1891. The 
effect of the Bordeaux mixture, however, was plainly observable and a 
rough estimate made October 19 of the percentage of foliage still upon 
the unbudded stocks shows the Bordeaux to be much superior to the 
ammoniacal solution, and 6 treatments superior to 5. 
quince leaf-blight (Entomosporium maculatum L6v.). 
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 observation 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 50 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-groAver 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 Bordeaux mix¬ 
ture and partly Avitlr ammoniacal solution.!

cides in the manner described on pp. 260-263. The season being an
