the eleventh concession of Dungannon to the mouth of the Papineau 

 Creek in the township of Carlow, there are a large number of lenticular 

 masses of nepheline syenite and alkali syenite intruded along the strike 

 of the crystalline limestones and amphibolites. Time did not permit 

 of a sufficiently detailed examination of this valley to accurately outline 

 all such masses, even if this were possible with so heavy an accumula- 

 tion of drift as is here found. The position, however, of certain of 

 these occurrences is shown upon the geological map which accompanies 

 the general report on the district to which reference has already been 

 made. 



A little to the east of Papineau Creek, nepheline syenite is met with 

 on both sides of the river, while farther down the river a little north 

 of Foster's Rapids, an extremely basic nepheline rock occurs. Still 

 fartlier to the east Dr. Miller mentions nepheline syenite outcropping on 

 a ridge in the ninth concession of Carlow, about one and a half miles 

 north-west of Campbell's bridge on the York river. No very detailed 

 examination was made of the area between Carlow and Brudenell, but 

 corundum syenites occur in the eighteenth and nineteenth concessions of 

 Raglan and in 'the first concession of Radcliffe, close to Palmer's rapids 

 on the Madawaska river, while nepheline syenite has been found on lot 

 25 of the nineteenth concession of Raglan. 



All these last mentioned occurrences in Raglan and Radcliffe be- 

 long to another and parallel band of these syenite rocks, which, starting 

 from lot 14 of concession XIV of the township of Carlow, where 

 corundum was first discovered by Ferrier, extends eastward through the 

 two northern concessions of Raglan, having been traced a short distance 

 east of the Madawaska river near Palmer's Rapids. The occurrence of 

 nepheline syenite and the closely related red syenite in the fifth and 

 seventh concessions of the eastern part of the township of Brudenell, with 

 their north-west and south-east strike, cannot be correlated with either 

 of these bands, although they occupy an intermediate position between 

 these and the Algona and Sebastopol occurrences on the east. 



Extending eastward from Brudenell a very wide belt of rocks of 

 closely related syenite types covers the northern portions of the town- 

 ship of Lyndoch, extending thence into Sebastopol and South Algona, 

 as far as Clear Lake, and probably beyond the Ottayva river into the ad- 

 jacent Province of Quebec. 



From the township of Tjutterworth where, as above mentioned, the 

 mos.t westerly development of these rocks is found, the occurrences of 

 nepheline syenite, if wo except that in Methuen, are thus confined to a 

 narrow and somewhat sinuous belt of country having a general north-east- 

 erly strike and which reaches the Ottawa river in the township of South
