MISCELLANEOUS INTELLIGENCE. 21 



constant circulation is effected. The apparatus is as simple as it is complete 

 and economical, and will, without doubt, be very generally adopted in hor- 

 ticultural buildings. Mr. Corbett is foreman at Mr. Pontey's nursery, 

 Plymouth, where the apparatus is iu operation. 



Protecting Flower Seeds, &c, from Birds, by means of Black 

 Thread or Worsted.— It has been very satisfactorily proved, this summer, 

 under my own observation, that Mr. Anderson's (of the Botanic Garden, 

 Chelsea) discovery of black thread being a far better protection against tire 

 depredatious of the house -sparrows in gardens than thread of any other 

 color, is much more serviceable than it was lound to be by Mr. Anderson 

 himself. That indefatigable guardian of his plants could not secure the 

 flowers of his extensive collection of crocuses from the attack of sparrows by 

 any means he could devise, until he employed black lines, stretched over the 

 flowers ; which proved a complete defence. 



The effect of black lines if attributable to their invisibility till the birds 

 are seated under them; but looking up, they are terrified at what they fear 

 is a snare suspended over them, and immediately fly away.
