LUCAS : VESTIGES OF ANCIENT FOREST.

And the beautiful Hues in " Robin Hood" — 
" In somer when the shawes be sheen. 
And leves be large and lang." 
leave nothing* wanting to prove this. 
' Shaws ' are frequent on the moors far above the present 
limit of tree -vegetation These Shaws are generally boggy 
ground, sheltered or associated with crags or rocky places. Thus 
there are no trees on " Feather Shaw," 1250 feet ; " West 
Shaw," 1200 feet; " Foulshaw Crags," 1000 feet; and many 
others. At present when a great elevation is attained by the 
stragglers, they are always found at the base of a bed of grit or 
sandstone, from which there is a perennial ooze or spring. 
These are just the places where the last vestiges of the ancient 
forests at these elevations would be preserved, and I do not 
hesitate to affirm my own belief, that they were in existence long 
since the coming of the Danes, and that a lowering of some 
hundreds of feet has taken place in the forest line within the last 
thousand years. 
OK THE SECTIONS OF THE DRIFT OBTAINED BY THE NEW 
DRAINAGE WORKS, AT DRIFFIELD. BY J. R. MORTIMER. 
The sections of the Driffield drains, to which I now beg to call 
attention, speak much for themselves ; however I deem it necessary 
to give a few explanations, and to express my views on certain 
features having a close relation to the beds shown in the sections. 
These sections were obtained in the year 1879, from personal obser- 
vations made twice, and occasionally three times, daily during the 
excavation of the drains, and from notes kindly given me by 
Dr. Wood, of Driffield. 
The drains run in the main nearly 1ST. andS., E. and W.; they 
embrace an area of nearly 40 acres, and in section give a total 
length of about G miles. They average a depth of about 8 ft.
