 .seen at a glance of what nature the fungous disease was, ;ind the effect they 

 have upon the crops. Accompanying the specimens there siiould be copious 

 notes in pam])ldet form pro\ ided for (Hstributioii among bu/id Jidr tillers of 

 the soil, giving as nearly as possible the time of appearance of the disease, 

 ;ind the proper time to apply remedies foi- checking the same. 



1 1' photographs could l)e obtained, showing tht' appearance of the plants 

 allected whilst in a fi'csli condition, additional interest in the specimens 

 would be the icsult, and thegrowci's would be thus enabled to more fidl\' 

 understand the disease and its eti'ect. 



y>y a ptopeilv oi'ganised system of exchanges, between the principal centres 

 of agricidture, horticultui-e, or fruit-growing districts, acting under instruc- 

 tions fi'om a properly e([uipped scientific central office, a good collection of the 

 various diseases could be built up in the districts most conceriu'd. and with 

 remedies to check the further spread of these, the result would be of inunense 

 value not only to the growers themselves but also to the State at large. 



As a preventive measui'e to check the further spread of the peach-rust. 



the " New Form of I'xirdeaux Mixture" is strongly recommended, which con- 



•sists of the follow ing ingredients : — 



Quicklime .. 4 11». 6 oz. Bhiestone (Sulphate of Copper) 4 11). () oz. 



Molasses ... 4 ,, G ,, \N'ater ... ... ... ... 2"2 gallons. 



Add the molas.ses to 13 gallons of watei, then slake the lime and add I. I 

 gallons of water to form a milk of lime. Pour this slow Iv into the swcetene*! 

 water, stirring briskly in order to mix intimately. Next, in a third vessel 

 (v^'hich must be of wooflen material) dissolve the bluestoiie, and |iour this into 

 the jM'evious mixture and stii' well. 



The first apj)lication of the New Itordeaiix .Mixture for ]»each and |<hMn 

 laist should be iuniiediately after pruning, sav. -I ulv-August. 



The seeoiul application should be applied just before the buds burst. A 

 third application should be applied when the leaxcs ai'»^ half tleveloped. The 

 <ipplication of this mixture is also beneticial if applied foi' Fcacli -leaf curl. 



The a,p))lication of ])otash manure is also veiv serviceable to check peach 

 and plum laist.

In 189i* I investigated these fungous diseases — Peach rust and Peach leaf curl. 

 also the Shot-hole in apricots, and experimented with Bordeaux mi.xture, 

 which certainly diminished the pest. P>ut the most (>tlicacious lemedy was 

 undoubtedly found in ade((uatelv feeding the ti'ees 100 peaches, nectarines 

 iirul apricots — growing in sandy loam. T added one ptiund of sulphate of 

 potash and half-a-pound of coppei-as (sulphate of iron) to the ordinary dose of 

 .six pounds of lionedust per tree, and these diseasrs absolutely di.sapjieai'ed in 

 three years from the orchai'd. The sui)se(|uenl ve:ii-s were notablv drv ones, 

 and, therefore, probably less favourable to the spread of fungous diseases; 

 but the very healthy aj)pearance of wood, leaf, and fruit of all the trees 

 convinced me that the addition of the above materials to the manure genei-ally 

 used on sandy soils for ftuit is advantageous. T found some varieties of trees 

 much more liable to these pests than others, and certain luii'.series famous, or 

 jathei- infamous, for sending out voung trees badiv infested. -H.C.L.A.
