HORTICULTURAL NOTES.

The Western New York Society met at Rochester, January 26.

_New Apples, Pears, Grapes, etc._--Wm. C Barry, secretary of the committee

on native fruits, read a full report. Among the older varieties of the

apple, he strongly recommended Button Beauty, which had proved so excellent

in Massachusetts, and which had been equally successful at the Mount

Hope Nurseries at Rochester; the fine growth of the tree and its great

productiveness being strongly in its favor. The Wagener and Northern Spy

are among the finer sorts. The Melon is one of the best among the older

sorts; the fruit being quite tender will not bear long shipment, but it

possesses great value for home use, and being a poor grower, it had been

thrown aside by nurserymen and orchardists. It should be top-grafted on

more vigorous sorts. The Jonathan is another fine sort of slender growth,

which should be top-grafted.

Among new pears, Hoosic and Frederic Clapp were highly commended for their

excellence. Some of the older peaches of fine quality had of late been

neglected, and among them Druid Hill and Brevoort.

Among the many new peaches highly recommended for their early ripening,

there was great resemblance to each other, and some had proved earlier than

Alexander.

Of the new grapes, Lady Washington was the most promising. The Secretary

was a failure. The Jefferson was a fine sort, of high promise.

Among the new white grapes, Niagara, Prentiss, and Duchess stood

pre-eminent, and were worthy of the attention of cultivators. The

Vergennes, from Vermont, a light amber colored sort, was also highly

commended. The Elvira, so highly valued in Missouri, does not succeed well

here. Several facts were stated in relation to the Delaware grape, showing

its reliability and excellence.

Several new varieties of the raspberry were named, but few of them were

found equal to the best old sorts. If Brinckle's Orange were taken as a

standard for quality, it would show that none had proved its equal in fine

quality. The Caroline was like it in color, but inferior in flavor. The New

Rochelle was of second quality. Turner was a good berry, but too soft for

distant carriage.

Of the many new strawberries named, each seemed to have some special

drawback. The Bidwell, however, was a new sort of particular excellence,

and Charles Downing thinks it the most promising of the new berries.

_Discussion on Grapes._--C. W. Beadle, of Ontario, in allusion to Moore's

Early grape, finds it much earlier than the Concord, and equal to it in

quality, ripening even before the Hartford. S. D. Willard, of Geneva,

thought it inferior to the Concord, and not nearly so good as the Worden.

The last named was both earlier and better than the Concord, and sold for

seven cents per pound when the Concord brought only four cents. C. A.

Green, of Monroe County, said the Lady Washington proved to be a very fine

grape, slightly later than Concord. P. L. Perry, of Canandaigua, said

that the Vergennes ripens with Hartford, and possesses remarkable keeping

qualities, and is of excellent quality and free from pulp. He presented

specimens which had been kept in good condition. He added, in relation to

the Worden grape, that some years ago it brought 18 cents per pound in New

York when the Concord sold three days later for only 8 cents. [In such

comparisons, however, it should be borne in mind that new varieties usually

receive more attention and better culture, giving them an additional

advantage.]

The Niagara grape received special attention from members. A. C. Younglove,

of Yates County, thought it superior to any other white grape for its many

good qualities. It was a vigorous and healthy grower, and the clusters were

full and handsome. W. J. Fowler, of Monroe County, saw the vine in October,

with the leaves still hanging well, a great bearer and the grape of fine

quality. C. L. Hoag, of Lockport, said he began to pick the Niagara on the

26th of August, but its quality improved by hanging on the vine. J. Harris,

of Niagara County, was well acquainted with the Niagara, and indorsed all

the commendation which had been uttered in its favor. T. C. Maxwell said

there was one fault--we could not get it, as it was not in market. W. C.

Barry, of Rochester, spoke highly of the Niagara, and its slight foxiness

would be no objection to those who like that peculiarity. C. L. Hoag

thought this was the same quality that Col. Wilder described as "a little

aromatic." A. C. Younglove found the Niagara to ripen with the Delaware.

Inquiry being made relative to the Pockington grape, H. E. Hooker said it

ripened as early as the Concord. C. A. Green was surprised that it had not

attracted more attention, as he regarded it as a very promising grape. J.

Charlton, of Rochester, said that the fruit had been cut for market on the

29th of August, and on the 6th of September it was fully ripe; but he has

known it to hang as late as November. J. S. Stone had found that when it

hung as late as November it became sweet and very rich in flavor.

_New Peaches._--A. C. Younglove had found such very early sorts as

Alexander and Amsden excellent for home use, but not profitable for market.

The insects and birds made heavy depredations on them. While nearly all

very early and high-colored sorts suffer largely from the birds, the

Rivers, a white peach, does not attract them, and hence it may be

profitable for market if skillfully packed; rough and careless handling

will spoil the fruit. He added that the Wheatland peach sustains its high

reputation, and he thought it the best of all sorts for market, ripening

with Late Crawford. It is a great bearer, but carries a crop of remarkably

uniform size, so that it is not often necessary to throw out a bad

specimen. This is the result of experience with it by Mr. Rogers at

Wheatland, in Monroe County, and at his own residence in Vine Valley. S. D.

Willard confirmed all that Mr. Younglove had said of the excellence of the

Rivers peach. He had ripened the Amsden for several years, and found it

about two weeks earlier than the Rivers, and he thought if the Amsden were

properly thinned, it would prevent the common trouble of its rotting; such

had been his experience. E. A. Bronson, of Geneva, objected to making very

early peaches prominent for marketing, as purchasers would prefer waiting

a few days to paying high prices for the earliest, and he would caution

people against planting the Amsden too largely, and its free recommendation

might mislead. May's Choice was named by H. E. Hooker as a beautiful yellow

peach, having no superior in quality, but perhaps it may not be found

to have more general value than Early and Late Crawford. It is scarcely

distinguishable in appearance from fine specimens of Early Crawford. W. C.

Barry was called on for the most recent experience with the Waterloo,

but said he was not at home when it ripened, but he learned that it had

sustained its reputation. A. C. Younglove said that the Salway is the best

late peach, ripening eight or ten days after the Smock. S. D. Willard

mentioned an orchard near Geneva, consisting of 25 Salway trees, which for

four years had ripened their crop and had sold for $4 per bushel in the

Philadelphia market, or for $3 at Geneva--a higher price than for any other

sort--and the owner intends to plant 200 more trees. W. C. Barry said the

Salway will not ripen at Rochester. Hill's Chili was named by some members

as a good peach for canning and drying, some stating that it ripens before

and others after Late Crawford. It requires thinning on the tree, or

the fruit will be poor. The Allen was pronounced by Mr. Younglove as an

excellent, intensely high-colored late peach.

_Insects Affecting Horticulture_.--Mr. Zimmerman spoke of the importance

of all cultivators knowing so much of insects and their habits as to

distinguish their friends from their enemies. When unchecked they increase

in an immense ratio, and he mentioned as an instance that the green fly

(_Aphis_) in five generations may become the parent of six thousand million

descendants. It is necessary, then, to know what other insects are employed

in holding them in check, by feeding on them. Some of our most formidable

insects have been accidentally imported from Europe, such as the codling

moth, asparagus beetle, cabbage butterfly, currant worm and borer, elm-tree

beetle, hessian fly, etc.; but in nearly every instance these have come

over without bringing their insect enemies with them, and in consequence

they have spread more extensively here than in Europe. It was therefore

urged that the Agricultural Department at Washington be requested to

import, as far as practicable, such parasites as are positively known to

prey on noxious insects. The cabbage fly eluded our keen custom-house

officials in 1866, and has enjoyed free citizenship ever since. By

accident, one of its insect enemies (a small black fly) was brought over

with it, and is now doing excellent work by keeping the cabbage fly in

check.

The codling moth, one of the most formidable fruit destroyers, may be

reduced in number by the well-known paper bands; but a more efficient

remedy is to shower them early in the season with Paris green, mixed in

water at the rate of only one pound to one hundred gallons of water, with

a forcing pump, soon after blossoming. After all the experiments made and

repellents used for the plum curculio, the jarring method is found the most

efficient and reliable, if properly performed. Various remedies for insects

sometimes have the credit of doing the work, if used in those seasons

when the insects happen to be few. With some insects, the use of oil is

advantageous, as it always closes up their breathing holes and suffocates

them. The oil should be mixed with milk, and then diluted as required, as

the oil alone cannot be mixed with the water. As a general remedy,

Paris green is the strongest that can be applied. A teaspoonful to a

tablespoonful, in a barrel of water, is enough. Hot water is the best

remedy for house plants. Place one hand over the soil, invert the pot, and

plunge the foliage for a second only at a time in water heated to from 150°

to 200°F, according to the plants; or apply with a fine rose. The yeast

remedy has not proved successful in all cases.

Among beneficial insects, there are about one hundred species of lady bugs,

and, so far as known, all are beneficial. Cultivators should know them.

They destroy vast quantities of plant lice. The ground beetles are mostly

cannibals, and should not be destroyed. The large black beetle, with

coppery dots, makes short work with the Colorado potato beetles; and

a bright green beetle will climb trees to get a meal of canker worms.

Ichneumon flies are among our most useful insects. The much-abused dragon

flies are perfectly harmless to us, but destroy many mosquitoes and flies.

Among insects that attack large fruits is the codling moth, to be destroyed

by paper bands, or with Paris green showered in water. The round-headed

apple-tree borer is to be cut out, and the eggs excluded with a sheet of

tarred paper around the stem, and slightly sunk in the earth. For the

oyster-shell bark louse, apply linseed oil. Paris green, in water,

will kill the canker worm. Tobacco water does the work for plant lice.

Peach-tree borers are excluded with tarred or felt paper, and cut out with

a knife. Jar the grape flea beetle on an inverted umbrella early in the

morning. Among small-fruit insects, the strawberry worms are readily

destroyed with hellebore, an ounce to a gallon of warm water. The same

remedy destroys the imported currant worm.

_Insect Destroyers_.--Prof. W. Saunders, of the Province of Ontario,

followed Mr. Zimmerman with a paper on other departments of the same

general subject, which contained much information and many suggestions of

great value to cultivators. He had found Paris green an efficient remedy

for the bud-moth on pear and other trees. He also recommends Paris green

for the grapevine flea beetle. Hellebore is much better for the pear slug

than dusting with sand, as these slugs, as soon as their skin is spoiled

by being sanded, cast it off and go on with their work of destruction as

freely as ever, and this they repeat. He remarked that it is a common error

that all insects are pests to the cultivator. There are many parasites,

or useful ones, which prey on our insect enemies. Out of 7,000 described

insects in this country, only about 50 have proved destructive to our

crops. Parasites are much more numerous. Among lepidopterous insects

(butterflies, etc.), there are very few noxious species; many active

friends are found among the Hymenoptera (wasps, etc.), the ichneumon flies

pre-eminently so; and in the order Hemiptera (bugs proper) are several that

destroy our enemies. Hence the very common error that birds which destroy

insects are beneficial to us, as they are more likely to destroy our insect

friends than the fewer enemies. Those known as _flycatchers_ may do neither

harm nor good; so far as they eat the wheat-midge and Hessian fly they

confer a positive benefit; in other instances they destroy both friends and

enemies. Birds that are only partly insectivorous, and which eat grain and

fruit, may need further inquiry. Prof. S. had examined the stomachs of many

such birds, and particularly of the American robin, and the only curculio

he ever found in any of these was a single one in a whole cherry which the

bird had bolted entire. Robins had proved very destructive to his grapes,

but had not assisted at all in protecting his cabbages growing alongside

his fruit garden. These vegetables were nearly destroyed by the larvae of

the cabbage fly, which would have afforded the birds many fine, rich meals.

This comparatively feeble insect has been allowed by the throngs of birds

to spread over the whole continent. A naturalist in one of the Western

States had examined several species of the thrush, and found they had eaten

mostly that class of insects known as our friends.

Prof. S. spoke of the remedies for root lice, among which were hot water

and bisulphide of carbon. Hot water will get cold before it can reach the

smaller roots, however efficient it may be showered on leaves. Bisulphide

of carbon is very volatile, inflammable, and sometimes explosive, and must

be handled with great care. It permeates the soil, and if in sufficient

quantity may be effective in destroying the phylloxera; but its cost and

dangerous character prevent it from being generally recommended.

Paris green is most generally useful for destroying insects. As sold to

purchasers, it is of various grades of purity. The highest in price is

commonly the purest, and really the cheapest. A difficulty with this

variable quality is that it cannot be properly diluted with water, and

those who buy and use a poor article and try its efficacy, will burn or

kill their plants when they happen to use a stronger, purer, and more

efficient one. Or, if the reverse is done, they may pronounce it a humbug

from the resulting failure. One teaspoonful, if pure, is enough for a large

pail of water; or if mixed with flour, there should be forty or fifty times

as much. Water is best, as the operator will not inhale the dust. London

purple is another form of the arsenic, and has very variable qualities

of the poison, being merely refuse matter from manufactories. It is more

soluble than Paris green, and hence more likely to scorch plants. On the

whole, Paris green is much the best and most reliable for common use.

At the close of Prof. Saunders' remarks some objections were made by

members present to the use of Paris green on fruit soon after blossoming,

and Prof. S. sustained the objection, in that the knowledge that the fruit

had been showered with it would deter purchasers from receiving it, even if

no poison could remain on it from spring to autumn. A man had brought to

him potatoes to analyze for arsenic, on which Paris green had been used,

and although it was shown to him that the poison did not reach the roots

beneath the soil, and if it did it was insoluble and could not enter them,

he was not satisfied until a careful analysis was made and no arsenic at

all found in them. A member said that in mixing with plaster there should

be 100 or 150 pounds of plaster to one of the Paris green, and that a

smaller quantity, by weight, of flour would answer, as that is a more bulky

article for the same weight.
