isophenal lines as well as of its isotherms." For these records 

 to be of value they should be kept for a series of years at 

 different stations. The leafing and defoliation of common 

 deciduous trees, the flowering of the same varieties of fruit- 

 trees, the blooming of Conhjline australis, Arundo conspicua, 

 and Phormium tenax ; these and many more equally easily 

 observed periodic phenomena would form an excellent record. 

 I have kept, but unfortunately too irregularly to be of 

 much use, a record for several years of the blooming of many 

 of the plants in my garden. A few extracts may be of in- 

 terest : — 



Chionodoxa sardensis bloomed on the 21st August, 1895 ; 



10th August, 1896 ; 6th August, 1897 ; 19Lh August, 



1899.

August, 1895; 13th August, 1896; 25th August, 1899.

5th September, 1896. 

 Anemone nemorosa bloomed on the 5th September, 1896 ;

 Kniphofia macoiveni bloomed on the 5th January, 1893 ; 



3rd January, 1895; 10th January, 1899. 



Of much greater value is a comparison of the blooming, 

 &c., of the same plants at different elevations and in different 

 regions. The following may be accepted as fairly correct : — 



Straiuberries are ripe near the seaboard at the beginning 

 of December ; at the Bealey (640 m. altitude), about 

 the first week in February. 



The double daffodil blooms in the Christchurch district 

 during the first and second weeks of September, and at 

 Castle Hill (723 m. altitude) towards the middle of 

 November or a little earlier. 



Fagus cliff'ortioides comes into new leaf-growth in Tarata 

 Garden, New Brighton, towards middle of October, 

 and at Castle Hill towards first or second week in 

 November. 



Ranunculus lyallii blooms in cultivation near Christchurch 

 from the beginning of October, on Arthur's Pass 

 (911 m. altitude) at end of November and begin-
