 A YORKSHIRE PLAN BY WILLIAM SMITH. 



Any record of the work of William Smith, the 'father of 

 English Geology,' is so very important, and year by year is 

 becoming more and more difficult to trace that it is essential 

 we should as far as possible make careful note of anything 

 of his that turns up. 



Among a collection of Yorkshire maps which I recently 

 purchased, is a lithographed copy of a map of South York- 

 shire which does not appear to be referred to by John Phillips, 

 Smith's nephew and biographer, in the scarce ' memoirs of 

 William Smith,' published in 1844, nor is it referred to by 

 Woodward, Judd, or other more recent writers. The lithograph, 

 which is reproduced herewith (page 282), is described as ' Pro- 

 posed Aire and Dunn Canal to drain the contiguous lands and 

 to shorten and connect the present navigations. — ^Wm. Smith, 

 1819.' In the bottom right hand corner is a note to the effect 

 that the map was ' drawn on stone by J. Phillips.' The year 

 1819 is that in which the greatest proportion of Smith's maps 

 were published, and presumably this map was issued in con- 

 nection with a prospectus, as it is fooslcap size, folded in four, 

 and has on the back of one of the folds ' Aire and Dun (sic) 

 Junction Canal and Extensive Drainage in Yorks. Printed 

 by E. William's, 11, Strand.' — T. Sheppard, Hull. 



I rientalis europea L. at Bradshaw, Yorkshire. — 



Midsummer this year. Dr. Woodhead and I visited Soil Hill, 

 Bradshaw, where we found Trientalis europea L. in plenty and 

 flowering freely, and I am happy to say showing no signs of 

 becoming extinct. The late J. Bolton (1775) records it as 

 occurring ' on a moor in Bradshaw, about the pipe-clay pits,' 

 this station is identical with the one we visited. I think I 

 am correct in stating that this is the most southern station for 

 this plant in Britain. We noticed one feature which is perhaps 

 worthy of a record. On a sloping piece of ground the Tri- 

 entalis was found growing plentifully among Nardus stricta 

 and Vaccinium Myrtillus. On a careful examination of the 

 underground parts, it was distinctly noticeable that the 

 Trientalis sent down its stem considerably helow the gi"ass 

 tussock, where it spread out its rhizome at right angles to the 

 stem axis, and the long rootlets descending from the rhizome 

 fed at a lower level than those of the Nardus stricta. A similar 

 Complementary society was noticed at Castleton, in Cleveland, 

 where Trientalis is abundant and is comparable to that of 

 Sphagnum, Calluna and Lister a cordata of our moors. Bolton 

 writes of L. cordata as growing at Causeway foot where Tri- 

 entalis grows. I am afraid the former has not been seen there 

 for many years. — W. Cash, Halifax.
