Suggestions as to Dipping of Sheep, [feb., 



there seems to be an indication in the reduced differences in the 

 returns of 1904 that the influence of the manures on the quality 

 was becoming somewhat less in the fourth season, as it was also 

 on the quantity of pasture produced. 



The best returns were got from the basic slag, but the super- 

 phosphate, though more costly, also proved an effective manure. 

 It must be remembered, however, that the figures of gain and loss 

 are only of value for comparative purposes, and cannot be taken 

 as representing the profit or otherwise which would be obtained 

 from the use of manures under ordinary farming conditions. 

 Under such circumstances the conditions would probably be 

 more favourable to the use of manures. 



Suggestions as to the dipping of sheep have been issued in 



Leaflet 61 as regards the prevention of Sheep Scab, and in 



Leaflet No. 145 in regard to the pre- 



Suggfestions vention and destruction of other parasites, 

 as to Dipping* 



of Sheep. such as keds and lice. In the course of 



the dipping which was carried out last year 

 in Scotland, of which an account has already been given in this 

 Journal, December, 1905, p. 516, several points came under the 

 notice of the Board's Inspectors in regard to which some sug- 

 gestions may be made supplementary to the information given 

 in the above-mentioned Leaflets. 



Cleansing of Dipping Tanks and Balks. — The importance 

 of cleansing the bath and of renewing the material from 

 time to time is not always sufficiently recognised. Where large 

 numbers of sheep are put through the bath without any steps 

 being taken in this direction, the solution must of necessity 

 become very dirty and mixed with urine, dung, soil, shed wool, 

 &c, together with the ova of the various parasites which are 

 washed out of the fleece. 



A good deal in the way of cleansing might be done by passing 

 a wooden rake over the surface of the solution and along the 

 bottom of the bath, thus removing the larger particles of wool, 

 rubbish, &c. 



Cleaning of the Catching Pen. — After each lot of sheep have 

 been through these pens, the pens should be thoroughly swept
