At the Meeting of the 15th of May, Mr. John Nairn, 

 Gardener to Thomas Forbes Reynolds, Esq. of Carshalton, 

 exhibited a plant of Cactus triqueter, on which three other 

 species of Cactus, viz. C. flagelliformis, C. speciosus, and C. 

 speciosissimus, had been grafted. The appearance of these 

 different plants thus united was singular, and the elevation of 

 their weak branches on the strong upright stem of the plant 

 into which they were worked, is advantageous in the display 

 of their fine blossoms. Mr. Nairn thus describes the opera- 

 tion of grafting, which may be performed any time between 

 the months of March and September ; — " I take a small part 

 of the plant I propose to engraft, and attach it by cutting 

 away a slice of the fleshy part of the stock, taking off also 

 from the piece to be attached, a small portion of the flesh, 

 to secure its adhesion ; the sap is so glutinous that the 

 piece will adhere without tying, but it is most adviseable to 

 fasten it with bass, great care however, must be taken not 

 to bruize it, for such an injury will cause it to rot. A 

 union will soon be formed, and the graft will grow freely." 

 Mr. Nairn has observed that the pendant direction which 

 the grafted Cactuses take, causes them to produce their blos- 

 soms not only more abundantly but earlier. He recom- 

 mends a compost formed of five parts of rich garden loam 

 and one part of bog mould, as best suited to their growth. 

 They should be placed in pots in the green-house or conser- 

 vatory, and be freely supplied with water during the summer,
