Obs This most delicious of all our fruit is pretty extensively cultivated here--though few take sufficient - 

 nains to procure and propagate the best varieties. The tree, unfortunately, is short lived,-ch!efly in con- 

 ienuence of the ravages of a worm at its roots, against which every device, hitherto essayed, seenij to be 

 iimvailino- There is, perhaps, no certain preservative, but a frequent and careful mspection of the roots, 

 and a removal of the insect-a more correct knowledge of the habits ot which is very desivable. 



It is proper, however, to mention, that an ingenious expedient was suggested about three years ago, by 

 David Tovvnsend E«qr. of tins Borough, which is now in process oi trial, and bids fair to answer a valuable 

 nurnose The attempt has been repeatedly made to insert the peach on a plum stock, on account of the 

 rno s of' the latter being less subject to the ravages of the worm: but the two trees are so dissimilar that the 

 neach does not thrive well on a plum stock. It occurred t. Mr Townsend, that as tne Apricot appeared 

 to be more nearly related to the peach, it would prob.jbly atford a more cxingenial stock. Accordingly, 

 he inoculated plum stocks with apricot buds, (which take very readily.) and as soon as the iaiior had 

 e-rown sufficiently-say the succeeding year,— he inserted peach buds on the apricot branches; thus making 

 a sort of three-story, or trii^le tree. The result has, so far, been equal to his most sanguine e.\pectations. The 

 nf^ach branches are flourishing vigorously; and there is every prospect of the experiment succeeding com- 

 ijietclv '^ very few vears will test it fully: and if it sinould answer present expectation, it will prove to 

 be a very important discovery. It would, perhaps, answer the same purpose, to raise Apricot stocks 

 at once in which to insert the peach buds: but as plum stocks are eveiy where aounuant, it was lound more 

 convenient, and expeditious, to resort to th" foregoing method. 



rig=The Nectarine.— a delicate urtWeii/ of the Peach, with smoother fruit,— is very little known, as 

 yetTin this vicinity; though it has latterly been introduced.

J{ab. Hedgei. 15 to 20 feet high: flowers white; berries red, small. Nat. Virginia, &c. 



Obs This thorn was introduced into this vicinity about 2^ years ago, for the purpose of hedging; and is 

 now prottv extensively cultivated lor that object. The plant is readily propagated by the seeds,— which it 

 produces in abundance.-and grows rapidly. When proper care is taken, (and it is worse than useless to 

 undertake it without proper care,) a good liedge can be obtained in about ten years troin ihe tinie of plant- 

 in - the seeds. It has been objected to this thorn, that as it is oi sucU rapid gr9wth, it will piobably be short 

 lived This objection will have some weight, if it shall prove to be well tounded: but, as Dr. 1' ranklin 

 remarked, in relation to the longevity of the Anglo- Americans,— we cannot yet determine that question; for 

 those wliich were first planted are still living, and flourishing in full vigor, home very respectable far- 

 mers condemn hedges altogether, and recommend fences m preference: but it is in vain to recommend fen- 

 ces to those who have no timt>er— and he wlio will inspect a perfect hedge— sucU as mny be seen in the 

 neighborhood of Mr. Caleb Kirk's factory, oa the Brandy wme,— will reqjine nuarisument to convince hiin
