During the fourth and fifth years the trees commenced bearing, and the product was fifty dollars per acre. The sixth and seventh, $100 per acre, and the eighth, ninth and tenth years, an average of $200 per acre.

The annual cost of labor and for fertilisers, was fifty dollars per acre. The above statement does not include the amount of fruit used, nor that given away, which waft very liberal.

The following will give some little idea of the prices received for the fruit. Bart-lett, extra fine, from $1 to $1.50 per dozen; first class Bartlett pears, $4 per bushel; second class, $2 per bushel; Vicar of -Winkfield, Lawrence, and Easter Beurre, gold for $24 per barrel; Duchesse d'Angouleme and Beurre Clairgean (extra specimens) from $3 to $5 per dozen.

The peach crop in Pennsylvania, until the past few yean, was a decided failure, owing mainly to the prevalence of the dreaded "Yellows;" fortunately, however, this has in a great measure passed away, and at the present time we are enabled to turn our attention to growing this fruit with profit. But in this connection I desire to impress upon fruit-growers in this State, that as the climate of Delaware and Maryland is so well adapted to maturing the earlier varieties in advance of us, it is prudent in us to turn our attention to the later kinds, which we are capable of producing of unexcelled sue and beauty. For instance the Crawford's Late, a magnificent peach, is perhaps as profitable with us, and will pay as large a percentage on the capital invested, as any fruit that can be grown. I know of one instance where the crop of this variety alone sold for 94 per bushel. Taking into consideration the length of our seasons, late peaches will very generally succeed satisfactorily. One orchardist informs me he has disposed of $700 worth of peaches from one and three-quarter acres, mostly of the Smock variety, although the "rot" of the past year reduced the amount considerably.

Another neighboring orchard consisting of 1,000 trees, realised the sum of $900, and, says the owner, "had all the varieties produced as well as did the Crawford's Late, it would have brought four-fold more".

All the larger fruits pay with varying success, depending greatly on the vicissitudes of a changeable climate. That apples will pay has been abundantly proven, if sufficient attention be given the trees. Insects have to be fought, and diseases counteracted, but success will surely follow a systematic course of careful culture.

One branch of pomological industry has not received that attention which its merits desire. I allude to the forcing of fruits under glass. Many are deterred through ignorance in regard to the management of such structures, believing that they are at best, but expensive luxuries, and calculated for amusement alone. That this view is fallacious, I am enabled to prove from a statement kindly furnished me by the owner of an extensive structure, designed wholly for profit. The statistics, here offered were carefully compiled from an unimpeachable record, and therefore may be implicitly relied on. One of the buildings referred to, consists of a "lean-to" house, 100 feet long, and seventeen feet and four inches wide, including a four feet walk along the back. The rafters on the same are sixteen feet long. The other structure is built in the " double-pitch " style, on the north side of the former, and to which it is connected. The latter is fifty feet long, twenty feet wide, with twelve, feet rafters. The whole range is heated by one of "Myers' Upright Tubular Boilers," using 800 feet of iron pipe, that will hold one gallon of water to the foot.

In addition to this heating apparatus, the smoke flue is carried along the whole length of the house, and % stove is placed in the extreme northern end to be used only in excessively severe and windy weather.

The original cost of these houses is not definitely known, but as they were erected during the late war, when material and labor was at the highest point, one may judge that it was very expensive. The heating apparatus was placed in working order at a-goat of something over $700. The following is an extract from the statement of the owner: "For two years I had no fruit; the third year I think about 150 pounds; the fourth year a nice crop of 800 pounds. No account has ever been preserved of the quantity used, but only what was sold; neither have I the amount produced by any single vine, with one exception - a large vine in the South House (Black Barba-rosa, or a closely allied varied), which has fruited four years; the product of this, however, has been carefully weighed each year, and is as follows, viz.: The first two seasons forty-nine pounds, fifteen ounces each year; the next, seventy-two pounds; and the last, forty-nine pounds, eight ounces; but I am satisfied we have several Black Hamburgs that have produced forty pounds each for the past three years. Bowood Muscats that produce regularly from fifteen to twenty-five, and perhaps thirty pounds.

If I was obliged to have only three kinds of grapes in my houses, I should select the above named varieties from such as I have any knowledge. If there are any more profitable I do not know them. Beside the above we grow Golden Hamburg, Muscat Trouvernon. Grizzly Frontignac, Ac.

" The Muscat Trouvernon is a very constant bearer, with handsome bunches, but does not equal the Bowood in character. So with the Golden Hamburg, it is very elegant, but the Bowood is still more beautiful, and here, is as reliable as the Black Hamburg.

"Another objection to the Golden Hamburg is, it must be cut as soon as ripe, and still another, it bears full crops only in alternate years ; but I should not like to do without it, as it ripens several days earlier than the Bowood.

"The Grizzly Frontignac is not a popular market grape, the objection being to its color, which is neither white nor black; but on account of its earliness, a vine or two is no objection in a collection. We have discarded Mitchell's St. Peters, and cut out fifteen or sixteen Muscat Hamburgs. There is no objection to the last named on account of flavor, but the manner in which it ripens is very vexatious".

These vineries commenced bearing full crops during the summer of 1868, when the amount sold was 1,078 pounds, twelve ounces, and realized $1,367.44; the expenses for the season, for coal, labor, marketing the fruit, incidentals, etc, was about $670, leaving a net profit for the year of nearly $700. The year 1869 produced a crop of 1,097 pounds, eleven ounces, and sold for $1,147.20, at a net profit of $583.93.

The past year's profits was but about $367.86 ; these expenses include all repairs and additions to the buildings, as well as commissions paid for disposing of the fruit, Ac.
