This, I think, is an example of the great benefit that 

 the power of self-fertilisation confers on certain plants and 

 in certain circumstances. This moor is 800 feet above 

 the sea-level, is exposed to high winds and heavy rainfall, 

 and even at midsummer to low temperatures. The weather 

 that I experienced was far from being exceptional, and it 

 is quite conceivable that many seasons may pass when 

 cross-fertilisation by pollen from other plants is exceedingly 

 difficult if not impossible of attainment. Drosera, with its 

 scanty supply of weak roots, must depend under such con- 

 ditions mostly upon its seed-bearing for its existence ; and 

 the chance of its survival would be poor indeed if that 

 depended upon cross-fertilisation. 



Record Photography. 



By Alfred Watkins. 



Is it not the case that a member of a Field Club, whatever 

 branch of science he is most interested in, is emphatically 

 one who makes notes ? Mental notes they may be, written 

 notes they ought to be, and how vastly helpful it is if pic- 

 torial or diagrammatic notes are added. Here it is that the 

 aid of the camera should be called in, even if to supplement 

 the work of a fairly skilled pencil, for the photograph — with 

 its wealth of detail — occupies a different position to the 

 simple sketch, each being superior to the other for its own 

 purpose. 



With such an end in view how vastly more interesting 

 camera work becomes than if directed to the usual end of 

 securing portraits, houses, and things which have only an 

 interest personal to the photographer. 



The geologist and archaeologist especially can scarcely 

 afford to neglect the camera. And yet how little has been 

 done — for example — in landscape illustration of Physical 

 Geography. 



It is my aim once again to help with a few practical hints 

 those who wish to take up this means of illustration, and
