Damage by Frost. 
During tli© past week or two the weather 
all over the southern counties of England and 
the Midlands has been unusually severe for 
April. If it had come in March we might 
well have expected it, and the damage would 
not have been so great, because vegetation 
would not have been so forward. As has 
been quaintly stated by a writer, “ summer 
has set in with its usual severity.” The 
blossom of fruit trees has been greatly in¬ 
jured, and the crop cannot possibly be so 
good as might have been anticipated a fort¬ 
night ago. The flowers of Plums, Cherries, 
and, to a lesser extent, Apples and Pears 
have been injured. The incipient fruits, in 
some instances, where we have examined 
them, have been blackened, and therefore 
rendered useless. Where Tulips are grown 
in fully exposed positions, they have had a 
very trying time to contend with the cutting 
winds. In certain cases, however, they have 
been severely injured—both flowers and 
foliage—by the frost. That would, of course, 
refer to tender species, and not to the 
ordinary forms of Tulipa gesneriana. Oak 
trees are usually reputed to be hardy, but 
even our native species are liable to suffer 
when the young foliage is just advancing and 
still in the tender condition, and when of a 
bronzy and yellow colour. Some of the 
exotic Oaks have also suffered the loss of the 
young leaves, and even the shoots which have 
been made during the past few weeks have 
been shrivelled up. This w r ouId apply to the 
Chestnut-leaved Oak (Quercus castaneaefolia) 
and the Lucombe Oak (Q. Cerris lucom- 
beana). The leaves and young shoots of the 
Horse Chestnut have been considerably 
damaged in many cases. Some of the early 
Hawthorns which expanded their leaves 
early have been injured by the young leaves 
and shoots being dashed against the thorns 
and branches by the wind.

house, he first found one or two of the miss¬ 
ing cuttings. Further search led to'a little 
lieap of them. Presently his eye caught sight 
of a green mass amongst the branches of a 
Plumbago. These, then, were the remainder 
of his hundreds of Lobelia cuttings, now 
built into a wren’s nest, only partly finished. 
He 1 ©called the fact that he had just scared 
a wren that morning when he opened the 
greenhouse.

What is American Weed ? 
The Editor of the “American Botanist” 
has been complaining about the vagueness of 
certain writers in “Nature Notes.” They 
have been writing about a plant which they 
indicated by the term American Weed, but 
the Editor rightly says that there are many 
American Meeds, not only in that country, 
but also in this. In some instances we re¬ 
gard them as beautiful, and in most cases 
they certainly are interesting. In a few cases, 
at least, the American Weeds which have 
found their way to this countiy have been 
choking up the streams and ponds, while in 
more shallow ditches plants of another kind 
would fill them up with a weedy vegetation, 
in some cases highly interesting to the 
botanist at least. In this latter case we 
refer to Impatiens biflora, otherwise known 
as I. fulva. We surmise, therefore, that the 
American Weed referred to by the writers is 
Elodea canadensis, generally termed Water 
Thyme in this countiy. It has had many 
other names, some of which are more apt, 
quaint and plausible than polite. We think, 
therefore, that the Elodea is the plant re¬ 
ferred to, because, although originally hailino- 
from America, it now fills up many streams, 
ponds, and even the shallower lakes, unless 
the aquatic birds are sufficiently numerous to 1 
keep th "Weed down.

Strange Conduct of a Wren 
We have under recollection a case where a 
gardener was planting Cauliflowers, and, 
after having planted a considerable number, 
he paused in his work and looked behind 
him. Almost every Cauliflower which he 
had planted had been pulled up by a tame 
Jackdaw, which had followed him closely 
while at work. On being remonstrated with, 
he merely said “ Caw,” and retired to> a safe 
distance. A correspondent called our atten¬ 
tion to a somewhat similar but far more 
annoying case. A gardener had made some 
hundreds of cuttings of the ordinary bedding 
Lobelia, and inserted them in boxes in the 
greenhouse in the usual way. On going in 
one morning he found nothing but empty 
boxes and proceeded to make inquiries in 
certain quarters as to who had removed the 
cuttings. No one could account for their 
disappearance. Proceeding to inspect the 
Buttercups and Violets. 
In this countiy many plants are termed 
Buttercups, and possibly an equally large 
number are termed Violets, although the 
latter term is usually applied to plants be¬ 
longing to the genus Viola in modern times. 
According to the Editor of the “ American 
Botanist,” it seems that both of the above 
terms are more loosely applied even than in 
this country. We are somewhat surprised, 
however, when he speaks of a species of 
yellow Violet to which the name Nuttallia is 
given. The plant grown in this countiy 
under the name of Nuttallia cerasiformis be¬ 
longs to the Rose family, and is somewhat 
like a Cherry, as the name indicates. It is 
certainly not a Violet, and we should hesitate 
to say that it had gold enough to be classed 
as a yellow Violet. Possibly the Editor will 
help us out of this difficulty.
