tersea village on the south side of the lake to the shore of Dog 

 lake, two miles distant, communication can be made with the 

 Rideau canal. 



Belleville Near the city of Belleville marl also occurs, but no data 



are to hand regarding its extent. It is presumably not so exten- 

 sive as the Sheffield deposits. 



Yonge Tnp. In the towuship of Yonge, near the village of Athens. 

 Athens J^p(j jp close proximity to the line of railway from 



Westport to Brockville, there are several deposits of marl which 

 have never been exploited. One ot these is on lot 13 range VIII., 

 and is said to occur over an area of at least 25 acres, with an 

 ascertained depth of seven to fifteen feet. The material is also 

 reported as occurring on lots 7, 8 and 9, range IX, in the bottom 

 of Mud lake, and possibly at other points in the vicinity. 

 South Eimsiey, In the towuship of South Elmsley it is found underly- 

 Bass Lake jpg- portions of Bass lake, with a thickness of three to 

 four feet, but the exact extent of the deposit is uncertain. This 

 place is but a short distance from the foot of the Rideau lake at 

 Oliver's Ferry. 



Wiiberforce In the township of Wilberforce, near the Bonnechere 

 Mink Lake river, and about three miles from the line of the Cana- 

 dian Pacific railway between Douglas and Eganville, is Mink lake. 

 This lake has an area of over 1,000 acres, the marl being visible 

 at many points and probably occupying most of the bed of the 

 lake. The thickness of the deposit has been proved to be at least 

 nine feet in places and may be much greater in parts of the lake 

 basin. The area can be easily drained so as to expose a large 

 surface of the deposit. 



McNabTnp. In the township of McNab the lower end of White 

 White Lake \ake shews a large area of the marl, extending over 

 some 700 acres, and ranging from five to seven feet in depth. The 

 area could be readily drained so as to expose a large body of the 

 material, but the distance from the town of Arnprior and railway 

 communication is about eight miles. It is about the same distance 

 to Glasgow station on the Canada Atlantic. 



Ross Tnp. In the township of Ross, several deposits are found in 

 Green Lake connection with a chain of lakes which extend south- 

 east from Muskrat lake, near Cobden village. On one of these,
