182 QUEENSLAND AGRICULTURAL JOURNAL. [1 Maz., 1900) 
I have now very much pleasure in handing you herewith, under sep , 
cover, a complete plan and specification of the dip planned, erected, and wol™ 
by me-with every success. 
The plan is only a rough one—not being drawn to scale—but is, 1)! 
sufficiently descriptive for the purpose for which you require it. 
accompanying “key” will, I think, be sufficiently clear, and the estimate 
cost of erection is quite reliable. 
In my letter to the Queenslander I stated that ‘“‘a dip to treat 1,000 
per day can be erected—other things being, of course, equal—for the su! 
£45, including all the ingredients necessary to charge the pool.” 
It was principally owing to the fact of all ‘things being equal” that i 
enabled to erect the dip so cheaply, and I do not see why others should not 
able to do so as well as I myself have done. 
Some three years ago, when dips were first spoken of—and it appearely 
if they were likely to be at least partially successful—I looked round m@- 
some very much cheaper and at the same time equally effective mee 
treating the stock, when the washpool of the early days came to my if 
After thinking the matter over, I found a suitable waterhole, and a good SUP 
of saplings within a mile of the site. 
After calculating the quantity of timber required for the work, I put i 
on to cut it, and three weeks from the day I started I had the first mob of @ 
through the solution. 
et 
All that is necessary is for a community of settlers to select a wat 
within a reasonable distance (say one mile) of a good supply of st™ 
saplings, and the rest is easy.

The solution I used is known as Masterton’s—tar, soap, and soda 5, 
tar, 8 oz. soda crystals, and 4 oz. soap to every {10 gallons of water 
quantity of tar and soap was never varied by me, but I was much more 2” y 
with the soda, as I honestly believe it was solely owing to the quantity 0?" 4 
T used that the ticks were killed at once. In short, my dip was charge py 
2 tons of soda crystals instead of one, and it is to this fact, and also the i 
the cattle were in solution, I attribute my great success. As my plan ® "a 
the distance from the slip to the landing place is 140 feet ; and during the | 
the cattle are travelling that distance, their points are being thoroughly *°* 
in a solution strong enough to kill a tick inspector, let alone a tick. 
Tustead of 83 hours, I always boiled my charge for 5; and when ready "| 
the pool, it was run into the middle of it by means of a spout. 
I put the tank on the bank of the pool from where we got the wally 
boil. Even when the solution was strong I used to put it in the tank to bo Fi 
extra soda—when I thought it was necessary to add any to the dip. By a? 
this plan there was no expense incurred in carting water. a 
Where necessary, stakes were driven in—close to the banks—and 0” ur 
the guides are tied so as to rest on the surface of the water. These guide 
the cattle moving in the direction of the landing. 
By means of a “float” which I had fixed up, I was always able to asia 
the quantity of water the dip had made—by leakage through the © ji 
between any two dippings of the stock, and boiled sufficient stuff to bri? 
solution up to the required strength again. @l

As I have already stated through the Press, I have put 521 head of A 
cattle through the dip in 24 minutes; and altogether 12,000 have be 
through without an accident. 
You have now all the information that I can think of at present. 
In conclusion, if a group of stockowners should decide to go in for. | 
these dips, my advice is do not spare the soda—an extra dose can do no }#
