MINERALOCy AND FOSSILS. 



8. Specimens: rock, minerals, and fossils. All specimens to bo 

 nimibered consecutively, and entered with a corresponding number in 

 a book kept for that purpose, witli the locality and date of collection, 

 and a sliort description of each. The numbers also to be entered in 

 the diary, on the day of collection (thus: June 15, ISGO, specimens 

 1 to 20, .stating whether rock, mineral, or fossil). 



9. As geological specimens are difficult to transport, owing to their 

 weighty character, it is desirable that only such as are new or doubt- 

 ful should be collected, and these should be as small as possible for 

 the purpose of examination and recognition ; also that whenever an 

 accurate description, or sketch, or both can be made to answer, they 

 should be resorted to in preference to adding unnecessarily to the 

 bulk and weight of the collection. 



In all cases the gross weight of the specimens that can be taken, 

 must be subject to the approval and control of the leader. 



10. llock specimens should in all cases be abandoned in favor of 

 either minerals, fossils, or recent natural history specimens. 



11. All specimens that it may be found necessary or deemed ex- 

 pedient to abandon, should be marked off in the catalogue, and the 

 date and cause for their being so abandoned stated. 



If fossil or recent natural history, sketches of them should, if 

 possible, be retained. 



MAPS, 



1 2. A tracing of the route, as laid down by the Surveyor, should be 

 furnished daily, if possible, to the geological and other scientific 

 officers, to enable them to mark the approximate position of their 

 observations. To effect this rapidly, the daily observations in the 

 journal should be numbered, and a corresponding number placed on 

 the map at the point where the observation was made, or to which it 

 refers. 



Boundaries of different rocks or geological formations crossed on 

 the line of route, should be marked on the map. 



SKETCHES, 



13. The observations, w'henever practicable, .should be copiously 

 illu.stratcd by sketches, with the number of the specimen or observa- 

 tion in tlic journal to which they refer attached. 



A sketcli of each camp and its environs sliould, if possible, be 

 made before quitting it. 



Sketches of all remarkable geological sections are desirable, also 

 outline views of mountain ranges, remarkable hills, and other physi- 

 cal features on either side of the line of route; also of all objects of 

 natural history and natives (aborigines).
