THE Board of Agriculture and Fisheries are collecting-, as oppor- 

 tunities arise, reliable data relating to forestry and afforestation, 

 and as an example of one of the types of information considered 

 desirable, the reader is referred to the account of the Coombe 

 Plantation in the Board's Journal for July and August, 1910, Vol. 

 XVII. , pp. 265-283 and 353-370. 



The data collected in any one locality will, as a rule, be incom- 

 plete, but it is hoped that, as the work of investigation progresses, 

 it may be found possible to co-ordinate the results into a form 

 which will be a useful and fairly complete guide to those under- 

 taking planting operations. 



In publishing the following investigations into the growth of 

 timber on mountain soils, the Board desire to thank the executors 

 of the estate of the late John Naylor, Esq., for permission to visit 

 and measure woods and to fell sample trees on the Brynllywarch 

 Estate ; and also the agent, Mr. P. Hurlbutt, and the sub-agents, 

 Messrs. Burn-Callendar and Beadon, for valuable assistance in 

 carrying out the work.
