CATTLE DIP. 
The following formula of a dip for the destruction of cattle ticks has been 
adopted by the Stock Department. It will be recognised as the Departmental 
Dip :— 
Arsenic oc = on PS oalb! 
Caustic soda ... as re pts Ls 
Tallow... on ah +H ecepeame Bs beni 
Best Stockholm tar ... nh ... 23 gallons 
Water ... aS dis: Res .-. 400 
Directions For Preparation oF Dip FRoM THE ABOVE MEDICAMENTS. 
(a.) Half fill with water a 5-gallon drum, add 2 lb. of caustic soda, and 
boil; then add slowly;8 lb. arsenic. Add cold water in small quantities to 
prevent overboiling until drum is full. 
(d.) Boil 100 gallons of water in a 400-gallon tank; add 2 lb. of caustic 
soda, then 8 lb. of tallow, and boil quickly. Add slowly in a thin stream 
2% gallons of Stockholm tar. When the whole of the tar has been added, boil 
from thirty to forty minutes, then add the solution prepared in accordance with 
instructions in (a); gradually fill the tank with water and keep the mixture 
boiling until the tank is filled. 
A MODEL CATTLE-DIP. 
The illustrations herewith, taken by Mr. E. P. Dyball, afford excellent 
representations of his brother’s (W. H. Dyball’s) cattle-dip, on his dairy farm, 
Greenbank, Yandaran, near Bundaberg. 
Tt is built after the plans of those supplied by the Department—that is, so 
far as the cement pit is concerned; but Mr. Dyball thinks they have improved 
on it'in the matter of the draining-yard, more especially for dairymen, viz.:— 
Instead of an enclosed square or triangle yard, they have made a long cement 
bottom crush, and consider that by the time the cattle walk through it they 
have drained sufficiently, and will thus cause no stoppage, but can go through 
in one continued string, without the horning, &c., they are subjected to ina 
small yard, which is a great consideration with milkers. 
There is a great difference of opinion regarding the proper position of the 
water and the “get-in” lip of dip. In Messrs. Dyball’s opinion, the. fluid 
should be about 8 inches below the end of lip, so that the beast can see that it 
has to jump; otherwise, if the water is above the lip, it deceives them, and 
often causes accidents to their legs, or they turn a complete somersault. 
They have put through several hundred cattle and horses now, and have had no 
mishap. 
Anyone wishing for more detailed account of the above dip, I should be 
most happy to give them.
