34. Notice regarding the Ionian Melon and the Malta Melon. By 

 Mr. Daniel Crichton, Gardener to the Right Hon. the Earl of 

 Minto. Read August 2. J 827. 



The Ionian green-fleshed melon is an excellent early or 

 summer fruit, and the Malta melon is an excellent fruit either 

 for summer use or for keeping. If grown late in the season, 

 and cut before it is too ripe on the plant, it will keep many 

 weeks. The silver medal. 



35. Notice regarding the Cause of Canker, the Natural History/ of 

 the Red Spider, 8fc. By Mr. Wm. Blair, Mount Stuart. Read 

 March 1. 1827. 



Mr. Blair is of opinion that the canker arises from an un- 

 fitness in both soil and climate ; and, as a bad soil makes a 

 bad climate, he concludes that the best way to prevent the 

 canker is to form gardens only on fertile soils. Many hardy 

 as well as in-door plants are liable to be infested with the 

 red spider, of which there appear to be several species. 

 Mr. Blair paints the bark of the stems and branches wholly 

 over with a mixture of tobacco liquor, sulphur, and a little 

 turpentine during winter ; and no insects of any kind appear 

 during the following summer.
