Appendix No. 31. 

 SuBVEY OF Islands in the Georgian Bay, District of Parry Sound. 



Toronto, March 28th, 1911. 



Sir, — In accordance with instructions from your Department dated April 16th, 

 1910, to survey certain islands in the Georgian Bay, together with shore line in 

 front of the Townships of McDougall, Carling and part of Shawanaga, I have ' 

 the honor to submit the following report. The work was commenced by retracing 

 the southerly limit of the line between Lots 30 and 31, Concession 11 and 

 Lot 20, Concession A, Township of McDougall, from its intersection with the 

 westerly limit of Church street in the Town of Parry Sound, through to the 

 shore of Georgian Bay, where a five-inch pine post was planted, one chain from 

 the lake shore, where the traverse of the shore line was started and carried 

 continuously from Sta. here to Sta. 410 on the Concession line between 

 Concessions VIII and IX, Shawanaga. 



Posts of the most' durable wood obtainable were planted at intervals of one 

 mile or thereabouts at prominent points along the shore in cairn of stones and 

 marked consecutively from W 1 to W 25 in Roman numerals. All the original 

 Township lines were searched for and found and marked whenever possible. In 

 several cases no traces of the original lines were to be found. All islands in 

 front of the above townships were accurately traversed either with transit and 

 micrometer or transit and chain, and in every case, posts of the most durable wood 

 obtainable were planted in a cairn of stones at a prominent point at a safe distance 

 from high water and marked consecutively in Roman numerals from IC to 405C, 

 and as far as practicable all islands were tied by triangulation to points on the 

 traverse of the main shore. 



I found it impracticable in a great many cases to divide up the larger 

 islands into parts containing not more than 10 acres as per your instructions, 

 or to post them so that they might be so divided on the plan. In other cases, 

 the larger islands were not marked with division posts because of information 

 either from plans in my possession or from other sources that they were patented. 

 In the case of Sandy Island, the plan in my possession did not conform very 

 accurately with the present shore line, and islands shown as Ingersoll, Gertrude 

 are now part of Sandy Island, due to the recession of the water of Georgian Bay, 

 some 5 or 6 feet since the survey was made in 1881. The island shown as 

 243C at the north-east corner of Sandy Island, is now part of Sandy Island, there 

 being no channel between them. 



In the case of Franklin Island, traverse was made with triangulation from 

 point to point and sub-traverse of bays made with transit and micrometer. 



Posts were planted at prominent points as nearly half a mile apart as possible, 

 and marked successively from F 1 to F XV. The work was carried on with all 

 despatch and speed commensurate with accuracy, although considerably hampered 

 with continual rains until well on in the month of June. 



The traverse of the shore liiie was carried to the northern boundary between 

 Concessions VIII and IX, Shawanaga, on October 21st, 1910, all islands along 

 the main shore being, tied by triangulation to the shore traverse on the way north 

 and traver^d on the way south.
