BUP Oak {Quercus macrocarya). By Gifford Pinchot [U.S.A. 

 Dep. Agr. Forest Service. Circ. 56; revised August 5, 1909). — This 

 tree is one of the largest and most valuable hardwood trees in North 

 America. It derives its name from the mossy fringe about the rim of 

 its deep acorn cup. It grows best in deep, rich, fairly moist, and well- 

 drained soil. The wood is very strong and durable, the heartwood 

 making excellent fence posts and railway ties. — V. G. J. 



Cabbagre, A Strain Test of * Jersey Wakefield.' By 



0. E. Myers (U.S.A. Exp..Stn. Pennsylvania, Bull. 96). — Two years' 

 statistics of the cultivation of the above cabbage have been collected, 

 with a view to fixing, if possible, the desirable characteristics of the 

 type. 



At present this cabbage, though often satisfactory, cannot be 

 depended upon to produce good heads, is uncertain in seed germina- 

 tion, in the time it takes to mature, and is often untrue to type.

Cabbagre Hair-worm, The (Mermis albicans). By F. H. Chit- 

 tenden {U.S.A. Dep. Agr., Bur. Entom., Circ. 62 ; Eevised Jy. 28,1908; 

 1 fig.). — The author describes in detail the panic which spread through 

 Tennessee and the neighbouring States in 1903, when reports were 

 circulated on the poisonous character of the Cabbage hair-worm. Among 

 these reports one stated that there was sufficient poison in one hair- 

 worm to '* kill eight persons." 



The reports have been proved to be quite erroneous and the cabbage- 

 worm entirely harmless.— 7. G. J. 



Canning: Vegetables in the Home. By J. F. Breazeale 

 {U.S.A. Dep. Agr. Farmers' Bull. 359 ; illus. ; 1909).— The writer 

 gives his experience of canning vegetables successfully at home. Glass 

 jars with wide mouths are always advisable. 



Three successive cookings of an hour to an hour and a half in a 

 closed container at a comparatively low temperature are infinitely better 

 for preserving colour and flavour than cooking for a short period at a 

 high temperature, or for a long period in an open vessel. 



A jar which has a glass cover kept in place by a wire spring is at 

 present the best pattern on the market. With new rubber rings it 

 can be used indefinitely. 



To test the success of the operation the spring should be lowered 

 and the jar picked up by the top. If satisfactory the top will net 

 come off. — G. H. L.
