crop of pears perfectly worthless. I have subsequently pointed it out to 

 gardeners in other situations ; and I suspect that it often exists unnoticed, 

 and greatly injures the quality of the pear. I washed my pear trees with an 

 infusion of tobacco in the spring, which appeared to have destroyed the in- 

 sects, but they appeared again in great numbers, and the frequent use of the 

 engine did not prevent their doing considerable injury. Not impropably an 

 infusion of the green leaves of either the Nicotiana tabacum, or N. rustica, 

 which miglit have been obtained at a very small expense, would have de- 

 stroyed or driven them off; but it did not occur to me to try it." (^Hort.

Trees at Faw/ei/ Hall. — Have you had anj' account of the trees at Fawley 

 Hall, which, I understand, are almost equal to tliose at Studley, of which you 

 have given such beautiful portraits in the Arboretum ? — T. B. S. Liverpool, 

 Sept. 1. 1837. [We have not, and should feel extremely obliged to any reader 

 who will procure it for us. — Cond.'] 



Waterh'g Vegetables with a Solution of Soda. — A solution of soda has been 

 applied with great success to the watering of vegetables. The difference be- 

 tween vegetables so treated, and those watered in the usual way, is very con- 

 spicuous. Vegetable marrow in common mould, when tiiis process has been 

 applied, has been found to surpass plants grown in a bed of dung. The 

 proportion of soda used is 1 lb. to 14 gallons of water. (Morn. Chron., 

 Sept. 20 ) [We should be glad to have some authenticated particulars on 

 this subject. — Cond.] 



Fungi 071 Vine Leaves. — A correspondent having brought us some vine 

 leaves from a vinery in the neighbourhood of Camberwell, the under sides of 

 which were covered, more or less, with a yellow fungus, we sent some of them 

 to Mr. Sowerby, who, in answer to our request that he would let us know the 

 name, sa3s, " The production upon the leaves of the vine (which is by far 

 too common) belongs to the genus of i<'Lingi Erineum of Greville; but I do 

 not know what specific name it has, unless it be the E. I'itis, which is very 

 probable. It has been by some thought to be caused by wounds inflicted by 

 some minute insect or mite ; and for that reason, perhaps, has been omitted 

 by Berkeley, in Hooker's English Flora. It is most probably a diseased state 

 of the cellular tissue, producing hair similar to that in the Plica polonica." —
