Mr. Editor. - The past, has been a season of unusual scarcity of fruit in this section, and indeed seems to verify the assertion that raising fruit seems to be attended with a great deal of uncertainty.

Grapes were the only crop of Autumn fruit in this whole region, with the exception of a few Peaches, Pears, and Apples. One orchard alone containing a number of trees of the Kearosee. and White Apple of which I sent you a few last season (now called White Winesap). These trees had a pretty good crop (I have not known them to fail twice in fourteen years)..

Can we not select such varieties as can be relied upon at all times? I have no trees to sell of these varieties, and therefore am not interested in bringing them out, but think there may be plenty of other good varieties that will bear in almost any season, if we could get hold of them.

Why is Horticulture not one of the branches taught in our Colleges, Academies, and Common Schools? Then men would begin at the right place when undertaking to raise fruit, and not spend a fortune and years of time in learning by sad experience, what they should have known before they commenced.

Depend upon it, a lecture once a month to the students of institutions of learning in the country, on the subject of practical Horticulture, would in a few years show a change in this important, useful and interesting branch of industry.

The time has come, when we may no longer plant a tree, and say live, prow, and bear fruit abundantly, as of old; there are other things to be taken into account.

The land is not new as it once was; alt the insects of the forests (uow cut away) bare taken up their abode in our orchards. Bugs, beetles, borers, curculios, aphids, etc, in hosts.

Clear away the grass and weeds around the trunks in the fall to prevent mice from barking, scrape off all moss in the spring, wash the trunks with strong soapsuds, look out for borers, and cut out, if any are found.

Prune every year to avoid cutting large limbs; keep up bonfires on calm nights in June, and destroy millions of mischievous insects; when your trees overbear, knock one half the fruit down when half grown, and you do much towards securing a crop the following year, Let no sods grow in your orchards, raise no wheat, rye, oats, or barley, in your orchards; beans, potatoes, and corn, will be much better; and for every good crop of Apples or Peaches, give a good top dressing of ashes and manure. Smoke your Plum trees three times a week with burning leather and mouldy hay, from the time the blossom has left until the fruit is nearly grown.

Cut the worms out of the Peach trees, level the earth again, and put a smalt circle of rock salt around them, or an old piece of strap iron, the rustier the better; open at one side so as to yield with the growth of the tree, this will be a remedy for one year at least.

Some one, and perhaps many, will say, all this is too much trouble, but it will pay. It has come to be the fact that the price of fruit, (like liberty,) is eternal vigilance.

Should life be spared me, and next season be a fruit one, we will report on this same subject. Yours truly, The Spy.
