the salt is dissolved mix the two solutions 

 and cook for an hour and a half longer. 

 Then strain and dilute to 15 gallons, and 

 xisie warm. Keep the mixture well 

 ag lated whilst spraying. Be careful not 

 to cook in copper vessels or spray from 

 copper knapsack pumps. 



RED SCALE OF ORANGE AND LEMON. 



Red Scale and Mussel Scale. 



Both these pests of citrus fruits should 

 have attention during the winter, as up to 

 2,000-3,000 feet above sea level their pro- 

 pagation is not influenced by the climate, 

 whilst at the same time their natural 

 enemies are affected. The di-y season 

 prevents the growth of the parasite fungus, 

 which destroys the scale in the summer, 

 and the predaceous and parasitic insects 

 are semi-torpid, and display no activity. 



MUSSEL SCALE OF ORANGE AND MANDARIN. 



For red scale fumigation with hydro- 

 cyanic acid gas, followed by sprayings 

 with resin wash, is recommended, whilst 

 the same wash or paraffin emulsion 

 should be used for the mussel scale. 

 Resin wash is recommended as a winter 

 spraj' for scale insects in preference to 

 paraffin emulsion, which is more suitable 

 for summer work. 



Resin Wash. 



Resin 12 pounds 



Caustic Soda (98 per 



cent) 2^ pounds 



Fish Oil pints 



Water 50 gallons 



Boil the resin, soda and oil with water, 

 and stir until dissolved, then cook for two 

 hours, adding hot water when necessary. 

 Dilute first with 25 gallons of hot water, 

 and dilute with further 25 gallons of cold 

 water when in spray tank. Use warm. 



Paraffin Emulsion. 



Soap li pounds 



Paraffin 5 gallons 



Water 2| gallons 



Use whale-oil, or common bar-soap ; cut 

 up well and boil until dissolved in the 

 water. Whilst boiling add to paraffin. 

 Ohurn violently, using the spray-pump, 

 to pump the liquid back upon itself, un- 

 til it is thoroughly emulsified. Dilute, 

 using one part of the emulsion to nine 

 parts of water. 



Locusts, 



Mr. Stock Inspector Brown's 

 Report. 



VTTRITING on the 1st inst., Mr. Brown, 

 ^ Stock Inspector, Lower Tugela, 

 writes :— " For the Avhole of the month 

 of J une no locusts have appeared in this 

 District. And from information received 

 from residents on the Zululand side, 

 for a radius of twenty miles, no locusts 

 have been seen. 



Very little grass has been burnt about 

 here ; the Natives have found out that by 

 burning the grass in large patches the 

 locusts are attracted at the time for laying 

 eggs."
