204 . = Lafedt in Apple-Trees.— Haydn and Clementi: 
ting down the tree, as Dr. Laf cured the 
tooth-acn by pulling out the termentor. 
In the fummer I appiied a trong fumiga- 
tion of tobacco, and found that it had 
“fuccefs on the part where it was directly 
blown; but this would be an endlels 
work in a large garden or orchard. Mr. 
Forlyth’s mixture is, perhaps, the beit 
known remedy, but that has effect no far- 
ther than to the part touched ; nor can it 
while the infect infinuates itfelf through 
the wood, and therefore, forit to be quite 
effeQual, every year would require a new 
anointment of thetree. ‘This featon very 
likely is the beft, before the infect has too 
much animation from the heat; but they 
are already vifibie in the interftices of the 
bark, and that piace where I {moked them 
is now rotten: indeed, it strikes me that 
the trees would eventually be injured if 
they were covered continually with a glu- 
tinous mixture, as their pores would be 
deprived of the free admiffion of air, and 
their refpiration would ceafe ; this mutt in 
the endkillthem. I have underftood that 
the infe&t appears more generally in gar- 
dens that have poplars around or near 
them, and I know in one inftance where 
this ornamental tree grows immediately 
oppofite a wall that was covered with 
trained apples, and which were deftroyed 
on purpole to fave the ftandards that were 
~ $n other parts of the garden; on feveral- 
of thefe. Mr. Forfyth’s mixture was 
brufked; but the trees are at length cut 
down, and their ftumps newly grafted. I 
have not been able to difcover any infe&t 
refembling the one in gueftion on the pop- 
Jar, but as I was paffing a hedge of elder 
T accidentally found my hand ftaied with 
the rednefs occafioned by killing them; 
and examining the branches on one of 
them, I found a large clufter, each about 
twice the fize of thofe on the apple, the 
‘down exaétly the fame, and the body in 
rings like them. ‘This tree, perhaps, fa- 
vours the growth of this deftructive infect, 
and it appears to me that a great ftep to- 
wards deftroying it would be to difcover 
what plant, &c. is moft numerous where it 
moft predominates. I tave found that 
hard rains, and water thrown on the tree, 
does not wath them off, as the long down 
on their backs appears to be oily like fea- 
thers. They are extremely tender, and 
the fkin is fo very foft that the touch of a 
knife in picking them of the bark almoft 
{ April 1, 
always kills them: they refemble greatly 
the cochineal infect, and a gentle rub with 
“the finger occafions its being ftained as if 
the perfon were wounded. Should any 
more obfervations arife to my notice in fu- 
ture, J-fhall with pleafure communicate 
them to-your Mifcellany.

SIR, 7 
MONG the numerous readers of 
your valuable mifcellany there are, 
no doubt, many whofe fondnefs for the 
{cience of mutic will give them an intereft 
in the following anecdote, connected with 
the fame of the great Haydn. A female 
friend coming to pals a. few days with me 
in the country, brought me-a piece of 
mufic, now before me; the following is 
the exact title: ** Haydn’s celebrated Air 
of God fave the Emperor, with Variati- 
ons adapted for the Piano-forte, by Mu- 
zio Clementi.”” Having by me a ¢opy of 
the fame air, with variations, by Haydn, 
which J purchafed four years fince at Vi- 
enna, great was my furprife, upon com- 
paring the two copies, to find that they 
were exactly the fame, with only the omil- 
fion of a few bars in the firft variation. 
How is it poffible to reconcile this feem- 
ing plagiarifm with the diitinguifhed cha- 
racter of fo eminent a compofer as Cle- 
meati ? 
F would willingly perfuade myfelf, as 
he is now abfent in Ruffia, that his name 
had been ufed, for the purpofe of impofi- 
tion on the public, without his know- 
ledge, but, unfortunately, the copy in 
my pofleffion was bought at his own fhop 
in Cheapfide. I fhall be happy to-hear, 
through the medium of your Magazine, 
any vindication of Mr. Clementi from fo 
degrading a charge, fince his character 
has hitherto ftood to juftly high in the ef- 
timation of the public. . 
Iam, Sir, your's, &c. 
Suffolk, Fan. 6, 1806, G, HE 
P. S. Can any of your mufical readers inform 
me the meaning of the term ¢* Poldca,” hav- 
ing confulted many dittionaries and mufical 
friends without fucceis. -
