200 TAGG—VEGETABLE REMAINS FROM THE SITE OF 
and one is justified in assuming that the vegetable remains from 
the same levels represent species of plants which were contem- 
poraneous with the occupation of the site. In the case of the 
woods associated with tools as handles, one has, of course, no 
direct evidence as to their origin. 
The general character of the various samples of earths from 
the pits and trenches, with the vegetable remains identified in 
each sample, is given in Table I. 
Table II gives the results of my identification of the separate 
objects, such as tool handles. 
In Table III I give a summary of the plant remains, arranged 
systematically according to the various natural orders to which 
the identified species belong. 
General Remarks upon the Material Investigated. 
I. Examination of Samples of Deposits from the Pits and 
Trenches. 
(For detailed descriptions of the deposits see Table I.) 
The plant remains identified among the samples are of three 
kinds :— 
(1) Specimens of woods and twigs identified by microscopic 
examination of their wood structure ; 
(2) Leaves and bark fragments recognised by their external 
appearance ; 
(3) Seeds and fruits. 
1. The results obtained by the examination of the numerous 
twigs and branches are somewhat disappointing. As an 
analysis of Table I shows, these results tend more to indicate 
the general prevalence of certain well-known indigenous trees— 
some probably pre-glacial—than to afford evidence of the presence 
in Britain at the period of the Roman occupation of this station 
of species of exceptional interest. Thus, ee a great number 
of twigs and branches have been examined ,and the species of plant 
to which they belong ascertained, I am only able as a result to 
tabulate some seven separate species of trees, and these are 
kinds which have always been considered to be indigenous.
