THE BINGERA DIAMOND FIELD. 99 



The following is an account of the number obtained by Messrs. 

 "Westcott and M'Caw from the Eagiehawk claim, up to August 

 26th 1873:— 



400 diamonds, 



weighing . . .

1,680 „ „ 803 „ troy. 



And, as examples of the number obtained per load of stuff, the 

 following may be cited : — 



5 loads yielded 86 diamonds, weighing 32 grains. 

 8 loads yielded 68 diamonds, weighing 30 grains. 

 Up to the present no large diamonds have been found, the 

 largest hitherto met with being one only of 8 grains 



1 of 4 grains 

 6 of 3 „ 



85 of 2 „ 



1,587 of less than 2 grains. 



No mention is made of the kind of drift from which the above 

 quantities were obtained ; they, however, afford an opportunity 

 of roughly estimating the yield. 



"It is reported from Bingera, in the Tamioorth Netos of Septem- 

 ber 26, that Mr. Grardiuer has obtained 115 diamonds, and that 

 the Grwydir Company are progressing vigorously. The Griant's 

 Knob is rich in gems, the yield averaging about 140 to the machine 

 full, when the dirt is taken from the diamond drift. 



"A correspondent of the Tamivortli Examiner, on the 12th instant, 

 states that there have lately been large finds of diamonds in the 

 district of Bingera. The dwydir Diamond Company have pro- 

 spected now twenty-one pieces of land, nineteen of which have 

 proved to be more or less diamond-producing soil, containing 

 Grupiara or alluvial deposit, whose surface shows it to be the un- 

 used bed of a stream or river ; Burgalhas, small angular fragments 

 of rocks, bestrewing the surface of the ground ; Cascalho, frag- 

 ments of rocks and sand mixed up with clay and forming the bed 

 of a river ; and Takoa Carza, which are the above materials cement- 

 ed together into a conglomerate mass. All the above, however, 

 are known by the generic name of Cascalho. The masses of 

 stones themselves, which rarely exceed a cubic foot in size, contain 

 itacolumute jasper, and perdots and granite. These are the 

 known iadications of the whereabouts of diamonds as trusted to 

 and found to be correct both in the East Indies and the Brazils. 

 The nineteen successful prospects of the Grwydir Company have 

 produced each on an average thirty-fiye diamonds to every six
