The following owners of estates, among others, have kindly 

 furnished us with specimens of living conifers for study and 

 comparison :— His Grace the Duke of Bedford ; the Marquis 

 of Headfort; Lieut. -Colonel Sir George HoKord ; the late Sir 

 Edmund Loder, Bart. ; Sir John Ross of Bladensburg ; Mr. G. W. 

 E. Loder ; Professor W. W. Smith (the Regius Keeper, Royal 

 Botanic Gardens, Edinburgh) ; Mr. C. Coltman-Rogers ; Mr. W. 

 Banks ; Mr. H. Clinton-Baker. To Sir John Stirling Maxwell 

 and Mr. F. R. S. Balfour we are indebted for the loan of photo- 

 graphs for reproduction ; and we have also to thank the Council 

 of the Royal Horticultural Society for permission to reproduce 

 illustrations from their Journal. Messieurs L. Parde and R. 

 Hickel, the well-known French authorities on conifers, in addition 

 to identifying critical species, have also sent us many interesting 

 specimens from the famous arboretum at Des Barres and other 

 French gardens and nurseries. 



Miss G. Lister, whose careful and accurate drawings are a 

 feature of the book, has made many useful suggestions, and her 

 assistance with the proof sheets has been invaluable.
