 Sinapis alba (White Mustard), Thymus vulgaris (Thyme) and Valeriana 

 officinalis (Valerian). 



The young angelica plants were brought from Hungary; part of them 

 developed excellently on the manured portion of the experimental field 

 when the dry spell in May was over, and in the autumn the plants stood 

 nearly three feet high and spread over an area of six feet. All the plants 

 on the unmanured portion of the grounds perished during the dry spell. 



For spearmint, manuring with nitrate of soda and potash appears to 

 answer best; superphosphate of lime also serves well. The slips planted 

 out on April 25 th , May 9 th and May 10 th especially developed excellently 

 during the period of heavy rains. 



Peppermint was planted out in the same way as spearmint and 

 flourished exceedingly. The much-feared peppermint "rust" or "snuff" did 

 not occur, — this pest appears to visit the plants more readily when they 

 are placed too closely together and when the leaves have been wet for a 

 long time. For this reason it is customary in England, during prolonged 

 spells of wet weather, to send two men, holding a rope taut between them, 

 in among the plants to draw the water from the leaves 1 ). 



In his fourth article on Philippine Terpenes and Essential Oil's, 

 R. F. Bacon 2 ) gives some interesting information concerning essential oils, 

 which we have included under the appropriate headings in the present 

 Report 3 ). 



Bibliography. 



R. T. Baker and H. G. Smith, the authors of A Critical research on 

 the Eucalypts, especially in regard to their Essential Oils*) which book 

 we reviewed a few years ago, have recently published a work on the 

 pine trees of Australia 5 ). This voluminous book contains not only the 

 botanical description of all Australian conifers at present known, but also 

 the results of extensive researches into the resins and essential oils 

 yielded by those trees, a subject on which nothing had previously been 

 published 6 ). 



It would lead us too far to discuss the botanical section of the book, 

 but we desire to refer to a fact of great importance from the standpoint 

 of phyto-geography. The subsection Abietince, which is the most widely-
