the surface, and is quarried for mending the roads. In these spots I 

 do not think any plants of interest have been noted. The oolite is 

 characterized by its peculiar fossils, as pectens, Terebratulse, Ammo- 

 nites, Belemnites, &c., many species of which are found in the stone- 

 pits near the town in great abundance. On the south side of the town 

 is Borough Hill, which is chiefly composed of sand, with nodules of 

 sandstone, and which probably belongs to the oolitic period. On the 

 top of this hill is a Roman entrenchment, within and on the borders 

 of which are found many rare plants : the hill has been enclosed 

 within the last fifty years. Three other hills on the other sides of the 

 town, viz., Newnham Hill, Fox Hill and Welton Hill, appear to be 

 composed of the same kind of sand as Borough Hill, but they are ra- 

 ther barren of interest in a botanical point of view. Two large reser- 

 voirs, formed for the purpose of supplying the Grand Junction Canal 

 with water, are situated within a mile of the town, and bear on their 

 margins a few aquatic and marsh plants worth notice, but from their 

 recent formation it is not to be expected that a great variety will be 

 found at present. Watling Street, one of the old Roman roads, runs 

 within three miles of the town, and contains one or two very interest- 

 ing species. 



Many of the plants which grow around Daventry are remarkably 

 local there, being found in only one or two spots : and this feature 

 prevails to a greater extent than I have noticed anywhere else. I 

 may just add that the following list is the result of a diligent investi- 

 gation of the neighbourhood within a distance of three or three and a 

 half miles from Daventry, during a residence there of between three 

 and four years.
