The. results in. the three sets are very contradictory in the 
months of June and July. The two young trees of 1887-91 
raised more than half their annual increase in June, whereas the 
adult of 1884-91 performed the same feat in July. In No. 3 
July was inferior to June, but not so remarkably as in the other 
two young trees. The result of all this is that the young trees 
agree in throwing the largest share of their growth into the first 
half-season, but in No. 3 the excess is slight, while in the others 
it is very great. On the other hand, the second half-season is 
greatly in excess in the adult tree. The latter, however, 
although healthy in appearance, grew at the rate of only about 
a quarter of an inch annually, so that the results are untrust- 
worthy. The two young Limes were also slow growers, and it is 
probable that No. 3 gives the most reliable results. They all 
agree in the smallness of the increase in the first and last 
two.months. 72 per cent. of the annual increase took place in 
June and July in No. 3,77 per cent. in the other two young trees,
