light. One word only as to the use of photography, 

 and that a warning — beauty in the view, while 

 always to be sought for, is only of secondary impor- 

 tance, and mere views taken without any particular 

 reason are seldom of use. The half-plate is best, as 

 it is a convenient size for reproduction afterwards, and 

 in the end saves much enlarging. The colours of coral 

 reefs are most attractive, and the author greatly desires 

 to see good photographs of them, with the different 

 colours represented with their true actinic values. 

 The expert photographer might try Wratten's Allo- 

 chrome plates, which will last for six months. In case

 the cut-out base of a tin.

 chisel end, as made for geologists (5s.) ; two strong 

 chisels (3s.) ; crowbar, 3 feet, with chisel and claw, 

 best steel, about 2 inches circumference, to be used as 

 a walking-stick on the reef (6s.) ; coarse forceps, a 

 common bent piece of steel with roughened ends, 

 about 12 inches long (is. 6d.) The above can be made 

 by an ironmonger who employs good blacksmiths ; 

 ready-made goods are not recommended. 



All nets, etc., can be obtained from the Marine 

 Biological Association, Plymouth. For merely reef or 

 shore work they can be dispensed with. The natur- 

 alist will have the benefit of the experience of the 

 Association to guide him. He should have all trawls 

 made rather heavier than is usual for temperate 

 seas. It is well to bring out fishing lines, hooks, leads
