information was laid against the Paris and Lyons Eailway Company 
because of the damages caused to the corn crops by the Mildew, 
wliich, the agriculturists maintained, arose from a hedge of Bar- 
berry several kilometres in length bordering the railway. After 
much argument, it was ordered that some part of the hedge, of a 
kilometre in length, should bo cut down, in order to try the effect 
on the crops : the Mildew diminished considerably. The wliolo 
hedge was then removed, and the disease disappeared. 
I am told that a very ugly epithet used to be attached to the 
paiisli of Kollesby, but that since the Barberry bushes in the 
liedges have boon destroyed, the Mildew has almost dLsappeared, 
and the epithet has been forgotten. 
Tiio conclusion tliat I would draw thus far is, tliat all Barberry 
bushes near corn-holds shouhl bo destroyed, and tliat even orna- 
mental shrubs, such as Berheris dancinti, B. ihdcts, B. nepulensls, 
A'c., should be e.xtirpated if they grow in places from which there 
is any chance of their infecting the corn. yEcidimn herheridis is 
not known to grow on l\Iahonias, Avhich are easily distinguished 
from the Barberries by tlieir pinnate leaves ; these, ^ therefore, are 
probably harmless. 
iho liarberi \ , however, is not the only offender. One species of 
^lildew is known to botanists as Puccinia tiframinis, and tlifters 
slightly from Puccinia graminis, in that its spores are shorter, 
broader, and less pointed than those of the latter. This Puccinia 
sfmminis has been produced from the spores oi^cidiuni asperifolii, 
a fungus which is found on various Boragineo^ such as hjeopsis, 
cinchusa, echium, &c. Ihese plants are not common at Mattishall, 
and as I have not found this ^Ecidium, I cannot say to what e.xtent 
the Wheat plants in Xorfolk may suffer from this particular source 
of disease. Some useful results might be obtained from a careful 
examination of these and other Boraginea> in the early summer 
months. The spores of ^Ecidium asperifolii are yellowish-white, 
whdo those of .Ecidium berberidis ave orange-coloured. These 
.Eddia are easily recognized, as the spores are contained in 
bright-coloured cups, plainly visible to the naked eye, growing 
on the surface of the leaves, or on the stems of the infected 
plants. 
Another important subject for consideration is the prevalence of 
these Puccinur on many of the wild Grasses which grow in the
