In response to a proposal made in 1908 {vide Trans., Vol. 
VIII., p. 618), we have devoted a part of our leisure in recent 
years to vegetation survey work. It was assumed that it might 
become a section of a much larger effort covering the whole 
county, but as there is no immediate prospect of this being 
carried to completion, it seems desirable to summarise the work 
done, rather than allow it to be entirely barren. The area dealt 
with covers fifty-four square miles, viz., twenty-four miles 
included in the four quarter sheets No. 51 of the six-inch 
Ordnance Survey ; six miles included in No. 87 N.E. ; and 
twenty-four miles in the four quarter sheets No. 37 S.W. and 
S.E., 50 N.W. and N.E. It lies between 1° 4 1 and 1° 21 1 
east longitude and 53° 43' 46" and 50° 31' 38" latitude. All 
the parishes of Attlebridge, Horsford, Morton-on-the-Hill, 
Spixworth, and Weston Longville are included, with parts of 
Alderford, Ashwellthorpe, Beeston St. Andrew, Braconash, 
Costessey, Crostwick, Drayton, St. Faiths, Felthorpe, Flordon, 
Frettenham, Hamford, Hapton, Haveringland, Hethel, Hor- 
stead, Honingham, Hockering, Lyng, Newton Flotman, 
Ringland, Saxlingham Thorpe, Sparham, Stratton Strawless, 
Swainsthorpe, Swannington, Taverham, East Tuddenham, and 
Great Witchingham. The first-named five quarter sheets 
were worked by one of us (W. H. B.), the remaining four were 
worked jointly. Sheet 51 was selected on the suggestion of 
Mr. Robert Gurney, the choice being influenced by the large 
proportion of uncultivated land, and irs situation near Norwich. 
Sheet 87 was chosen as a typical boulder clay area, contrasting
