 be recovered in two months. 



" I am quite convinced, however, that the sulphur will give me quite one maund of tea 

 per acre by the end of the year."

14th May 1893. — " I had bad luck as regards weather, March being a wet month this 

 year. Eeserving 2 cwt. for experimental purposes, the balance of 5 tons of flour of sul- 

 phur was applied to 135 acres, of which 85 acres had good sunshine for between ten and 

 fourteen days before being washed by rain ; 28 acres for two days ; and 22 acres were pow- 

 dered in the morning and washed in the evening. Still the effect seems to be much the 

 same over the whole area which is fractically free of spider. I qualify the latter statement, 

 as a bush every here and there does show up red this year, which was not the case in 1892. 

 The number is altogether insignificant, being under 1 per cent., but I mention the fact as 

 being curious and unlike the past season's experience. 



" The only point worth noting this year is, that a single day's good hot sunshine 

 appears suiBcient for the sulphur to do its work. 



"The 138 acres treated in 1892 have for the most part very little spider. Some of the 

 worst sections, especially those subject to flooding, show up a little red, but not one 

 ■quarter as bad as in former years ; on the other hand, there are large stretches with no 

 spider at all. 



" On the first signs I went over 72 acres with the one cask of 2 cwt; reserved for the
