increase in the first half of the season, but the great majority 

 rebounded much above their average in the second half. In 

 these two Poplars, however, the depression was prolonged 

 through the whole season, and their foliage had a very- 

 pinched look. Excluding the two bad years, their rate rises 

 to 145 and 1-32. 



P. alba. In tlie west belt of the Arboretum. Has a 

 crooked stem, and does not appear to be thriving. 



Like the otlier Poplars, its rate was reduced in 1888 and 

 1891, but even deducting these bad years the rate rises only 

 from 0-64: to 0-78. 



Carpinus betui.us. 



Ko. 81 in the well-sheltered east belt of the Arboretum ; 

 Xo. 86 somewhat more exposed, and in the thinner soil of 

 the south belt. 



The annual rate, 069 and 0'55, seems low, and it may be 

 questioned if the trees are thriving, as the foliage is rather 

 shabljy, and tlunr growth has been very irregular and not at 

 all corresponding in the two in the annual rise and fall. 

 The rate of a handsome symmetrical Hornbeam, No. 33, 

 standing free in the I>otanic Garden, and 4 feet in girth, 

 was only 0*41 for ten years. 



Fagus sylvatica. 



Both in the well-sheltered east belt of the Arboretum. 



The annual rates, 1'31 and 1-21, are higher than in any 

 of the ten much older I>eeches, some in the Botanic Garden, 

 others at Craigiehall, girthing respectively 60, 66, 70, 78, 80,
