of soil over limestone, such as carries the lovvlaiid pasture plants 

 up to a s^reat heig-ht, no chalk wolds and no cliffs of limestone 

 or basalt. I shall be j^reatly interested in seein<j the survey 

 extended to the North Riding, with which I am personally most 

 familiar. The hig^hest point of the hills included in this map is 

 1,900 feet, so that no portion of the area reaches up into 

 Watson's 'Arctic Region,' and the number of northern (Scottish 

 and Highland types of Watson) that occur within its bounds is 

 much smaller than in the northern tracts included within the 

 county. The nine photographs, by Mr. W. B. Crump, M.A., 

 of Halifax, show characteristic stations o{ different types, and 

 in the text a list of the commonest and most characteristic 

 plants of each type is given. This is the first area in England 

 that has been dealt with in this comprehensive manner. Two 

 tracts in Scotland, North Perthshire and the neighbourhood of 

 Edinburgh, have been similarly dealt with by the late Mr. Robert 

 Smith, whose death at an early age was a great loss to British 

 botany. Similar surveys have been carried out by Professor 

 Flahault, of Montpellier, in France, designed principally to show 

 the distribution of certain trees ; and a large number of photo- 

 graphs, similar to those of Mr. Crump, will be found in a book 

 published in iSgg by Professor Conway Macmillan, entitled 

 'Plant-life in Minnesota.' In the list of books cited H. C. 

 Watson's ' Cybele Britannica' is included, but not his more 

 recent 'Topographical Botany,' in which Yorkshire is divided 

 into five vice-counties, and a separate catalogue of plants given 

 for each. It is now nearly forty years since I came away from 

 Yorkshire, and it gives me great pleasure to see that a new 

 generation of botanists has arisen who are doing such thorough 

 and excellent work. J. G. Baker.

FISHES. 

 Pike at Hemphone Lock. — At Hemphone Lock, on the 

 river Hull, there is a weir and the water from the clews rushes 

 against a wall on the bank of the stream with great violence. 

 At this point during March a Pike of 2 lbs. jumped clear of the 

 water right on to the top of the wall, a perpendicular distance 

 of two feet, and was easily captured. There was a similar 

 occurrence a few years ago at the same place, the Pike in that 

 instance weighing 9 lbs. It is not at all remarkable for members 

 of the Salmon family to leap a considerable distance, but I have 

 seldom known Pike leap as high as recorded above. — H. M. 

 Foster, Hull, 9th May 1903.
