Detailed Estimates.

1. The following statement showing the profit to be derived from the systematic cultivation of wattles, was complied from the evidence given before the Board of Enquiry on Wattle Cultivation, Melbourne, 1878, and forms an appendix to their report. (The Board recommend A. decurrens note and A. pycnantha).

Receipts derivable from a Wattle Plantation of say 100 acres, planted in the manner proposed.

Each acre planted with wattles, 10 feet apart, would carry 400 trees; at the end of fifth year, trees would yield say 56 lb. matured bark; stripping only every third tree 333 tons would be obtained off 100 acres; this, at £4 per ton, would give at first stripping  £1,332 0 0 
In the sixth (or following) year, a similar number of trees would be stripped, the bark having increased in weight say 14 lb., the increased yield of second stripping would therefore be 400 tons at £4, making  1,600 0 0 
In the seventh year the remaining trees would be stripped, from which a still greater increase would be obtained, say 480 tons at £4, maknig  1,920 0 0 
The aggregate yield of bark during the first eight years, 1,215 tons, amounting in value to  £4,852 0 0

2. The following estimate is by Mr. J. E. Brown, and is taken from a report by that gentleman to the South Australian Legislative Council in 1884. (Mr. Brown recommends A. pycnantha):—

REVENUE  £  s.  d.  EXPENDITURE.  £  s.  d. 
To value of property increased and improvements, say  400  By purchase of 100 acres, at £3 per acre  300 
To value of 500 tons of bark, at £5 per ton  2,500  By cost of substantial fence all round, say, 1½ mile at £50 per mile  75 
By ploughing 100 acres, at 8s. per acre  40 
By of 30 lbs. of seed, at 1s. per lb.  10 
By labour, sowing the seed in rows, say, at 5s. per acre  25 
By scarifying between the rows twice, at 4s. per acre  20 
By thinning and pruning for two years, at 10s. per acre per annum  100 
By forming fire-breaks during the third to seventh year, say, £5 per annum  25 
By sundries  50 
By interest on money expended during the seven years, say  280 
By cost of stripping 500 tons of bark, at 25s. per ton  625 
By cost of carting same to market, at 10s. per ton  250 
Balance, being clear profit  1,108 
£  2,900  £  2,900 

Notes on above Estimate.—At the distances apart which I recommend the trees to be grown, namely, 4 to 6 feet, there will be an average of 1,200 trees to the acre. In order, however, to make due allowance for blanks, I base my calculations upon there being 1,000 only to each acre. £5 per ton is only two-thirds of the present selling price of bark. I give 5 tons as the probable yield per acre. That this is a low estimate will be admitted, when it is considered that this only allows for 10 lb. of bark to be taken from each tree. (J. E. Brown).

3. Estimate of expenditure upon and revenue from a wattle plantation of 100 acres, during a term of seven years, by Mr. G. Perrin, Conservator of State Forests, Victoria, 1889.

He recommends the cultivation of the broad-leaf wattle (A. pycnantha); broadcast sowing.

To vermin destruction, and unforeseen expenses, say  50

To final pruning about fourth year (superficial only), at 5s. per acre  25 
To interest on seven years' rental  £3  15

£1,534  18 
By 100 acres of wattle-bark from 1,200 trees to the acre, each producing 12 lb. of bark—642 tons, £7 10s. per ton  4,815
