hole in the bottom of the pot, and lay the rest of the vine 

 from the bottom of the pot in the ground : they thus shoot 

 much sooner. For such pur[X)ses, I take the old shoots that 

 are to be cut out that season. For the pots, I use the same 

 compost as for the border. I always keep rotten dung about 

 the pots, as it makes the vines strike much sooner than keep- 

 ing the pots dry. I have had twenty-six good bunches in a 

 pot, and could have had more but for thinning. When the 

 fruit is at maturity, I cut the old bunch by the bottom of the 

 pot, and remove the plant at pleasure for ornament. 



" I have often taken notice that, in some sorts of vines, the 

 foliage turns brown, just as if it had got a little frost. Such 

 vines are generally on a clay soil, or on a bottom tliat does 

 not let the roots push freely, so causing a stagnation of the 

 sap." 



53. Notice of a Hatvthorn Hedge, damaged hi/ JEcidium laceratum. 

 By Mr. Wm. Don, Hull. Read June 14. ISU. 



The hedge which surrounds the Hull Botanic Garden was 

 planted in 1812 ; and, in the summer of the same year, " sin- 

 gular brown swellings " were found on the young shoots. 



" Those protuberances, for the most part, occur in the mid- 

 dle of a young shoot, but sometimes towards the end ; and 

 vary in number from one to three, or more, on each shoot ; 

 frequently, even the leaves are similarly affected. Their most 

 usual shape is oval ; but they are often singularly curled and 

 distorted. In size, they vary from that of a bean to that of a 

 walnut. Exteriorly, they are sometimes smooth, but com- 

 monly present a brown shaggy appearance; which, when 

 examined with a magnifying glass, is found to arise from 

 numerous minute and thickly set orifices, each surrounded 

 with many leaves, and containing a brown powder, which at 

 one time was so abundant as to make a visible cloud when the 

 hedge was shaken. Interiorly, they are sohd ; but of a less 

 consistent and more brittle substance than the rest of the 

 shoot, without any appearance of being inhabited by insects 

 of any description. 



" With respect to the nature of these protuberances, there 

 seemed every reason, from the brown powder, to believe them 

 to be fungi of some kind ; and specimens having been sent to 

 Mr. Sowerby, that celebrated artist and botanist stated them 

 to be ^cidium laceratum of his English Fungi^ table 318.; 

 adding, that ' JE. cancellatum (t. 409. of the same work) 

 attacks pear trees, and often prevents valuable crops.' 



" Though I have made diligent enquiry, I have not met with 

 any one who has before observed the disease in this neigU-
