 But even when trees are stnng by these insects, if proper at- 

 tention is paid at an early stage, and every branch carefully 

 cut off in February or March, below where any appearance 

 of the canker extends, and these branches in which at this 

 period the eggs of those insects are deposited are immedi- 

 ately burned, such attention will, in a short period, totally 

 eradicate them. Still, if your neighbour has trees near at 

 hand which are thus attacked, it will be necessary that the 

 same course may be pursued by him simultaneously, other- 

 wise the insects which are winged will find their way from 

 his trees to your own, which would render your individual 

 efforts useless. To show the ease with which the difficulty 

 referred to can be remedied, I will merely mention, that in 

 my Nurseries, where there are more than 20,000 plum trees, 

 it is an uncommon circumstance to meet with a tree thus 

 attacked. 



32. Hulings' Sufierb. This plum, I have little hesitation 

 in saying, is the largest known either in Europe or America. 

 The largest white or yellow plum in Europe, as far as my 

 information extends, is the Yellow Egg, or White Magnum 

 Bonum, which is an oval fruit ; and the largest red or purple 

 plums are the Imperial Violet, Jerusalem, and some of the 

 ])runes. The Huiings' Superb I received from Dr. William 

 E. Hulings, of Pennsylvania, a gentleman distinguished as 

 much for his zeal and perspicuity in the introduction of new 

 and valuable fruits to proper notice, as for the extreme 

 liberality evinced in their dissemination to others. To that 

 gentleman I am indebted for the following remarks: " I 

 have had a fully ripe and delicious plum from my tree, 

 weighing three ounces and seventy-eight grains, and measur- 

 ing round six inches and seven-tenths." I saw the fruit of 

 this tree, which stands immediately beside a Washington 

 plum, and it was decidedly the largest of the two. The 

 fruit is of a roundish form and greenish colour, bearing 

 an affinity to the gage, from which it doubtless originated. 

 Were I to venture a supposition as to its parentage, I should 

 suppose it to have originated from the Green Gage, impreg- 

 nated by the White Magnum Bonum. It is three years 

 since I began to cultivate it, and I have already sent a num- 

 ber to different parts of the Union, and several hundred are 

 now in the Nurseries. In a more recent letter from Dr. H.,
