select shoots of privet of pencil thickness in August, cut them in 

 six-inch lengths, insert a hud (shield method), Figs. 13 and 14, and 

 then treat them as soft-wood cuttings until rooted. They were 



kept in coldframes over winter and 

 planted out the following spring. Sub- 

 sequently some trouble was experienced 



by reason of the growth of the under- 

 stock, probably because we did not 

 plant them deeply enough. 



Amateurs who require only a few 

 ot any variety and who are not con- 

 cerned with quickly producing a salable 

 plant are advised to propagate lilac 

 species by seeds, and varieties by 

 cuttings, layers, or suckers. Some 

 nurserymen doubtless will continue to 

 propagate lilacs with aid from privet 

 understocks, and it is difficult to see 

 any objection to this practice pro- 

 vided they are careful to ensure that 

 the understock is eliminated and the 

 lilacs are on their own roots before 

 being passed along to the ultimate con- 

 sumer.

INSECT PESTS AND FUNGOUS DISEASES Ob

Scale Insects. — Lilacs arc commonly attacked by several differ- 

 ent kinds of scale insects. Perhaps the most common one is Oyster 

 Shell Scale, which is brownish or grayish bark-like in color, and 

 curved like an oyster shell. When fully grown the scale is about 

 Vs inch long. The scale is produced by the female, which is found 

 underneath it during the growing season. Li the fall the cluster
