ACTION OF STRYCHNINE SOLUTION. 
Rererrrye to an article in the February number of the Journal, dealing with 
the destruction of noxious animals by poison, the bandicoot dose is given as 6 
m. grammes of strychnine, and the amount of strychnine on each grain of corn 
as 31 grains of 54 m.grammes. The result, mainly owing to the omission of a 
decimal is incorrect. 
The result arrived at by Mr. J. B. Jenkinson, Miriam Vale, is that each 
grain of corn will hold -03324 m. grammes, and a bandicoot or ecockatoo would 
have to eat nearly 185 grains of corn to get akilling dose. Mr. J. B. Hender- 
son, Government Analyst, puts it thus:—1l grain = 648 m. grammes. Thirty 
30 x 648 
50000 
corn, and to make a dose of 6 m. grammes (bandicoot dose) 6 + ‘04 or 150 grains 
of corn would be required. 7 
With regard to arsenic poisoning, Mr. D. Jones, Fruit Inspector, says that 
1 part of arsenic mixed with 2 parts of washing soda, dissolved in 1 gallon 
of water, is pretty sure to achieve the desired result. = 
grains strychnine in 50,000 “ corns’’ is = nearly ‘04 m. grammes per 
A DURABLE WHITEWASH. 
A corresponpEn® of the Journal complains that she was advised to whitewash 
her kitchen (a brick one) with freshly slaked lime. The lime was applied as 
directed, with the result that the walls presented the appearance of the hair of 
a kanaka after the customary lime bath—a dirty red colour. Here is a recipe 
- for whitewashing which ought to be good, seeing that it is used by the United 
States Government for painting lighthouses, &c. :—Three parts of fresh Rosen- 
dale cement and two parts of clean, fine sand mixed thoroughly with fresh 
water. In applying it, the wall must be wet with clean, fresh water, to be 
followed immediately with an application of this cement wash. During the 
application this wash must be kept well stirred, and be made as thick as can be 
applied conveniently with a whitewash brush. 
TO KIND THE NUMBER OF FEET OF BOARDS THAT MAY BE 
CUT FROM A LOG. 
From the diameter of the log in inches subtract 4 inches for the slabs. Then 
multiply the remainder by half itself, and the product by the length of the log 
in feet, and divide the result by 8; the quotient will be the number of feet. 
EXAMPLE. 
What is the number of feet of boards that can be cut from a log 24 
inches in diameter and 12 feet long ?
