 .special fault to be found with those described above, but simply because it 

 was the only possible one in the circumstances and for the purpose ; 

 In plac3 of pariodic observations made on a few selected plants during tbeii 

 gro^\i;h at one place, a large series of plants grown at widely different stations 

 are compared. Early in the life of the Cane-broedinn Station it was noted 

 that, as one passed from the frost -visited regi" Pmijab, in a south- 



easterly direction along the Himalayas and ill a southerly direction down the 

 Peninsula, one constantly met with larger varieties of canes, even when these 

 belonged to the "'same natural groups. It was easy to suggest that this was, 

 in the main, due to the forciug effect of the warmer, moister climate. And 

 seven North Indian canes of those collected at Ooimbatore were distributed 

 to TaUparamba, on the Malabar coast, and Samalkota on the Coromandel, 

 in order to note the effect on these varieties of the soil aiid climate. A scheme 

 of accurate msasuremefU-fe-^ijiAix^^WflQlj^^vft^^ time, and these ■soon 



showed that there were marked differences in the growtli of the plants in

dicotyledons is aware that they differ according to variations in the year's 

 season and those of successive years. At certain places in the Madras Presi- 

 dency, all the palmyra palms may be seen suddenly to narrow at about the 

 same distance from the ground, or to show a marked bend in the same direc- 

 tion, indicating surely that, at that period of growth, the young plantation 

 encountered some storm or period of stress^ (Plate II). In the cane itself it has

very kiadly placed at my di«po.sal a photograph taken by him of a palmyra tope, showing 

 the effect of a .storm ; and he has given me the following note concerning it : " The 

 photograph of the palmyra palms with bent trunks M'as taken in October 1911 in the 

 village of Mallavaram, in Cocanada taluk of the Godavari District. The tope was situated 

 ni-Ai- the sea shore The palms wore said by the village Mui\sifi to have been bent over in a 

 storm that oceiu-ed 28 years ago, and he was able to fix the date because it hapinmed in the 

 sime year a.-* an important domestic occurrence."
