1802] Hints towards ſecuringothèà Turnip Crop. 323

Conſidering te’‘importance of theiſubje@& tothe public, äl though[have obtained a/patent in thé year 1800, for’ framing maſts.pards, bowſprits, girders, êro. hollow ſo as to“ combine lightneſs with ſtrength, and though the method here deſcribed comes und#r the ſaecification, being'in fome degree hollow, yet as far‘as relares!to the leſſcning/the.coiſumption of Engliſh oak, and introducing the larch and other- firs of our own growth. into geherat uſe; T-ſhall give licenſes gratuitouſly to all thoſe who chuſeto apply to me for them, maſts, yards, bowſprits,&c. ex- cepted.

In ſome former obſervations which have been publiſhed, T have 5

proved the-ſuperior advantages.of hollow timber; eſpecially when expoſed to ſudden tranſverſe ſtrains or jerks, ſo that it appears to nie unneceſſary to ſay more on this ſubjed.

OT-haveſendeavoured to explain my ideas in as plain and ſimple amanner as 1 can, but if L ſhould’ not be clearly underſtood, L ſháll be ready to give any further information that‘may be wanted.

And am, Sir, your obedient ſervant, GEORGE SMART. Pratt-Place, Camden Town, May 17, 1802. A—

HINTS TOWARDS SECURING THE. TURNIP CROP

To the Editor of the Commercial and Agricultural Magazines

SIR, , S the Turnip ſowing ſeaſon is at hand I ſhall preſume ta

give a few inſtructions towards ſecuring of thar very cafúal, büït, at the ſame time, very valuable crop. in ſecuring niy tur- np crop I have, of late‘years, béen rather more fortunate than my neighbours; and if I can ſecure this, I reckon that the two fóllowing crops Will’prove frui:ful of courſe. This crop, TI an perſuaded, has more enemies“ than are generally reckoned in that number. Th my opinion, there 1s ſcarcely an inſect, that either takéS'its flight over, or that creeps upon thé ſurfacé of the ground, that does not delight ii feeding‘upon the“ tender leavés of this plant. It tas, likewiſc, önë enerùy, at leaſt, T mean the Grub of the Cockchafer, that does not appear above ground: but Tbelieve that irs'gréateſt foe is éhe’ intenſe heat of the fun. And this heat is not dnly än enemy of itſelt, bur the grand éncourager of others+ for the wärmtti-of the ſun enlivens. every ſpecies of in- ſe& for the attack, and at the ſame time checks the growth of this plant,‘ad’ probably makes ir füll ſweeter food tor its de- vourers. 1 always obíerve young turnips fail firſt, and in the greateſt degree, undér a hedge that faces the ſouth: there, a free circulation of thé air is obſtrudted, and there, the heat is increaſed by refledion.
