 of sufficient strength to support their fruit, and do not run 

 so much to barren vine, as seedlings are apt to do. His mode 

 of propagation is to put about four inches and a half of mould 

 into pots nine inches deep, in which he plants the cuttings 

 taken from the tops of the bearing branches of the old Cu- 

 cumber plants. He then waters them, covering the tops of

At the same time a communication on the use of Water 

 impregnated with Pigeon's Dung, as liquid manure, was re- 

 ceived from Mr. Meaens, and read at the Meeting on the 

 18th of April. He had experienced the advantages of this 

 liquid with his Pine-plants, which he had used at the sugges- 

 tion of Mr. Knight, and having some Cucumber plants in 

 the Pine-stove, which had been planted in January, but 

 which, in consequence of dull weather, had become weak 

 and of a pale green colour, he applied the liquid to the 

 roots, and in a few days a great change in the appearance 

 of the plants was produced : the foliage assumed a hardy 

 green, the shoots acquired an unusual degree of strength, 

 with short joints, and although the stove had scarcely any 

 air given to it, yet the fruit swelled off rapidly, and attained
