4/0 Grafting. — Turnip Fly. — Patents. 



ton, belonging to Lord Stewart, the gas ascended the staple and 

 suffocated William Osley, one of tlieni. Another buckled him- 

 self to the clasp, and was drawn to l)ank. A corf was let down, 

 and the other two fortunately got into it. and were brought up 

 almost dead. The gn-^ ascended the shaft of tiie pit, was ignited 

 at the engine, which also took fire, and continued burning till 

 between ten and eleven o'clock at night, when the gas exploded 

 in the pit. Tiie shock was felt three or four miles; the wood- 

 work of the engine was ail burnt. 



NEW METHOT) OF GRAFTING TREES. 



A common method of grafting, is by making a transverse sec- 

 tion in the bark of the stock and a perpendicular slit below it: the 

 bud is then pushed down to give it the position which it is to 

 have. This method is not always successful ; it is better to re- 

 verse it, by making the vertical slit above the transverse section, 

 and pushing the bud upwards into its position — a metliod which 

 rarely fails of success ; because as the sap descends bv the bark, 

 as has been ascertained, and does not ascend, the bud thus placed 

 above the transverse section, receives abundance, but when placed 

 below, the sap cannot reach it. Annales de Chimie, xi. 



TO PROTECT TURNIPS FROM THE FLY. 



Experiments made by Lord Thanet and Mr. Grey have con- 

 vinced them that lime sown by hand, or distributed by a^ ma- 

 chine, is an infallible protection to tnrnips against the ravages of 

 the fly. It should be applied as soon as the turnips come up, 

 and in the same daily rotation in which they were sown. The 

 lime should be slacked immediately before it is used, if the air be 

 not sufficiently moist to render that operation unnecessary. 

 These gentlemen have communicated the foregoing fact to the 

 Board of Agriculture.
