These measurements show that though the initial advantage was 
in favor of group 2, the increase in height made by group 1 in the 
first six months after transplanting was more than three times that 
made by group 2. In the first year the average height per tree for 
group 1 increased 11 inches, while that for group 2 increased only 
5.1 inches. That this more rapid growth of group 1 over group 2 
continued throughout the first two years is shown by the increased 
difference at each measuring between the average height per tree for 
the two groups. At the end of the two years the new growth, as 
measured by the increase in height, made by the trees which had 
been set with their roots in a ball of earth from the nursery was 
more than 43 per cent greater than that made by those which were 
transplanted with their roots bare of earth. This increased growth 
and vigor is most certainly worth a little extra labor and expense. 
The effect of the two different methods of transplanting was 
equally pronounced on the early yield of the trees. No trees what- 
ever were lost in the first year. Of the 156 trees comprised in group 
1, 53 trees, or 34 per cent, fruited at one year from setting, while of 
the 165 trees comprised in group 2, only three trees, or 2 per cent, 
fruited. As the first crop is usually small, it was not measured. 
In the course of the second year, one tree was lost from group 1 
and seven trees were lost from group 2. At two years from setting, 
148 of the 155 trees of group 1, or 95 per cent, were fruiting, while 
of the 158 trees of group 2. only 134 trees, or 85 per cent, produced 
fruit. The crop from each group was measured in unpulped coffee 
cherries and is shown in Table III.

In not a single picking did the yield from the second group ap- 
proximate that from the first. For group 1 the total yield amounted 
to 76.9 liters, and for group 2, 29.8 liters, or less than two-fifths as 
much as that of group 1. Here again the very marked influence of
