On the Resources of Victoria, §c. 141 



For setting out the Osculating Arcs. 



The distance of the stakes was assumed as 33 feet, or 05 chain. 



Cosec. = 2 _Z = 29 ' 3U x 2 = 29-314 x 4 = 117-256 



C -5 



The nearest cosecant was that of 30 v (in this case also). 



Then, by reversing the formula, 



c = 2 r sin. 30' = 58-628 x -0087625 = -4515 chain 



66 



= 29-8 feet 



The arcs swept through B and D, being staked out by setting up the 

 theodolite at A. 



N.B. — A fresh tangent at any point arrived at on the curve is 

 simply the deflected [_ 6 from a chord, i.e., from one of the lengths 

 (29 - 8 ft. in this case), and a subsequent chord is the deflection again 

 of 6 out of tangent, so that the deflection of chord from chord is 2 0. 

 This was shown on the ground, and the whole was understood by 

 several articled pupils who attended.

In reading this paper before you, I think it necessary to 

 mention that the subject of " Our Resources and their De- 

 velopment " have occupied my attention for a considerable 

 time. It was about the 9th of last July, when the news 

 first reached this colony of war having broken out between 

 France and Austria, that the propriety struck me forcibly 

 of making no longer delay in contributing my mite to incite 

 the inhabitants of this colony to the necessity of increased 

 action in providing for their national wants, by making them- 

 selves as far as practicable independent of other countries for 

 articles of agricultural produce, and also for manufactured 

 articles. 



I am sorry to say that, at the present time, the perusal of
