we also replenish the material removed by the crop, and we are strongly 

 impressed with the efficiency of green manuring. As in the previous year 

 we have carried out experiments with fertilizers, supplied by the manager 

 of the Potash Syndicate, Sydney. The test plots, which are the same as 

 those treated in 191 1, are each :|:-acre in extent. The results are as 

 follow : —

This shows a gain of exactly three-quarters of a ten between the unmanured 

 and plot No. 3. The value of this extra yield, at current rates, is jT^d. 

 while the total value of the crop, from the fulh -manured acre, is worth 

 £22 14s. 3d. 



In tabulated form are given the yields of the grapes from each stock. 

 Once again a caution must be given against attributing the disparity in 

 returns to the stocks. As previously ■ pointed out the crop recorded on 

 Rupestris du Lot is not fair to that stcck, for, being next to the road, 

 much of the produce does not reach our weighing machine. Growers will 

 also note that some of the stocks, used when the College vineyard was re- 

 planted to test their value, are now discarded as not quite satisfactory. 

 Of the new varieties we have, as far as possible, made the wine separately. 

 We have 16 lots of the.se varying from 5 to 10 gallons each. Wine- 

 makers will realize the immense amount of trouble and labour the careful 

 handling of so many small quantities has entailed, but will, we think, 

 appreciate the results. Some of the newer table varieties of grapes are in 

 cool storage to test their keeping qualities, and, consequently, their suit- 

 ability for the export trade.
