In the 1906-7 plots the difference was very marked. Mr. Park's plot 

 at Romsey showed a difference in favour of the local seed of i ton 7 cwt. ; 

 and Mr. Lane's at Koroit, 12 cwt. The difference in the appearance ot 

 the produce was much in favour of the local seed. In all these tests 

 efforts have been directed towards the improvement of the productiveness 

 of the Brown's River, or to discover a variety that would take the place

of that old favourite. The varieties used in this connexion were Black 

 Prince, Blue Prolific, and a variety grown on a small scale in a garden 

 plot under the name of Guernsey Blue. The latter has proved unpro- 

 ductive and lacks quality, and if it shows no improvement next season 

 will be classed out. Of the two former. Black Prince has given the 

 most satisfactory returns, taking Newlyn and Romsey as typical districts 

 for red skins. 



The soil of the Neerim and Trentham plots was similar and it will 

 be noticed that there is exactly the same difference in the value of the 

 crop in each place viz. ^3 15s. per acre, whilst the difference at Romsey 

 is ;^4 13s. 6d. This difference is mainly due to the fact that the 

 Brown's River crop throughout the Romsey and Lancefield districts was 

 destroyed by thrip, while the Black Prince was only very slightly 

 affected by that scourge. When grown under favourable conditions the 

 Black Prince is more elongated or kidney shaped than the Brown's River 

 as will be seen by the illustration which represents the best type of each 

 variety from Mr. Herbert's plot at Neerim.
