Of the deposits to the east of the boulder ridge — the sand half — 

 we have little information. The only section of consequence I 

 know of was a bore made for water about fifty years ago at Richard 

 & Co.'s works at twenty feet above the sea level. This revealed — 

 Garden soil, ... ... ... ... 2 feet 



Fine sand gradually becoming coarser, ... ... 18 ,,

In 1867, a section was exposed at the Chapel Works 1000 feet 

 from the present sea margin. Beneath 9 feet of pure sand, and 

 at about 4 feet above the main sea level; sea shells in abundance 

 were found. The condition of these shells left no doubt that this 

 was an old beach — not a sea bottom — buried beneath the blown 

 sand. The Links, extending between the mouths of the North 

 and South Esks, consists mostly of blown sand, gradually rising 

 by the growth of the bent and links grasses, and it is within my 

 own observation that the sand hills are gaining from the sea by the 

 agency of the lymegrass and sea mat weed. 



EXCURSION TO WOODS OF THE BUEN AND TO EDZELL 

 CASTLE. 



ON Thursday, 24th July, at 10 a.m., a large party of ladies 

 and gentlemen left Montrose in three brakes, and drove 

 along a picturesque route to the upper woods of the Burn. The 

 weather during the earlier part of the day was all that could be 

 desired. The interest of the drive was greatly heightened by the 

 forethought of Dr. Howden, who had prepared an itinerary, of 

 which a copy was given to each excursionist, and in which at- 

 tention was directed to each object of interest and to the geo- 

 logical features of the country along the route. Mr. Barclay 

 (Hon. Sec. of the Antiquarian and Natural History Society of 

 Montrose) also very kindly pointed out and described the geology 

 of the district visited during the excursion. 



Descending the left bank of the river the party enjoyed the 

 rugged grandeur of the scenery between the Mooran and 

 Gannochy Bridge. The botanists observed a few local plants by the
