108 On the Means of Destroying Wasps. 



glove on the left hand, in such numbers that my gardener 

 counted upwards of two hundred and twenty at one haul 

 from two Apricots. We then made more nets, and by per- 

 severance soon turned the tide, so that scarcely a wasp could 

 escape us, whether on espaliers or wall fruit, to feed being 

 certain death ; and we had consequently Moor Park Apricots 

 in perfection till September 16th, the Peaches and Nectarines 

 on open walls being also almost untouched. 



I wish that I could confirm the effects in attracting wasps, 

 attributed to Hoya Carnosa,* and Yew berries.f My gar- 

 dener saw not less than two hundred wasps on one bunch of 

 black Hamburgh Grapes, in a neighbouring hot-house, close 

 to a plant of the Hoya, in the richest flower, which was un- 

 touched ; and my own observations only go as far as a soli- 

 tary bee feeding on it. As for Yew berries, I saw wasps 

 passing numerously by an abundance of them in a very 

 thick hedge, in their way to the closely adjoining hot-house, 

 at Studley, in which the bags, improperly made of Scotch 

 gauze, (which by its transparency increases the temptation), 

 were eaten through, and full of these pests of the garden. 



I remain, 



Your's truly, 



Thomas Feankland. 



Thirkleby, near Thirsk, March 12, 1820.
