these four were omitted. The relative growth of new vine at 4 
months from planting bore an interesting relation to the length of the 
cutting, as the growth of each group more than doubled that made by

the group of cuttings of the next shorter length. The measurements 
at the end of 12 months showed that where cuttings of 3 to 13 nodes 
are used, every advantage is with the longest cuttings. 
In the blossoming season of the year following planting, at about 
16 months, three plants of the group of longest cuttings flowered, 
but no others. This indicates that in propagating vanilla long cut- 
tings are also preferable to short ones because they bring the vines 
into earlier production.
