Nahdowa Sahgi-River, until they got two or three severe defeats in 

 the vicinity of the Blue Mountains, by Sahgimah, the most celebrated 

 warrior of the Odahwahs at that time. Instead of vraiting for the 

 Mohawks at the Island, he used to come and meet them at the Blue 

 Mountains, hence that place is called to this very day, Sahgimah 

 Odahkahwahbewin, viz., Sahgimah's watching place. The last time 

 he met the enemy there he found them occupying his watching place. 

 In the evening he went to view their camp alone, he saw their arms 

 piled about the camp as if they suspected no danger, whilst their 

 warriors were feasting and dancing. He then went for his men, and 

 on his return he found the Mohawks had retired to rest. Having 

 placed his men in order, ready for attack, he entered the camp alone, 

 and removed the arms of the slumbering enemy. The Mohawks being 

 without arms were, of course, slaughtered, except a few who were 

 spared on purpose. The Odahwahs cut off the heads of the slain, and 

 fixed them on poles, with the faces turned towards the Lake. Sah- 

 gimah then selected a canoe, which he loaded with goods, provisions, 

 and ammunition, put the survivors in and told them to go home and 

 never to come there again ; he also desired them to say when they o-ot 

 home that they had met Sahgimah on the top of the Blue Mountains, 

 where he fixed the heads of their companions on poles, with the faces 

 turned towards the Lake, and that he declared his determination to 

 fix in a similar manner, the head of every Mohawk that he might fall 

 in with in that quarter.

Having been frequently called upon in the routine of that branch 

 of the Crown Lands Office to which I belonged in the year 1842, to 

 calculate the quantities of land contained in irregular figures, it struck 

 me that a set of transparent scales subdivided into parallelograms 

 and squares, accurately framed, to correspond with the usual scales
