THE NATIONAL NURSERYMAN 
Certificate of Membership in The National Association of Nurserymen 
Whoever originated the idea of a certificate showing 
membership in the National Association deserves credit 
for it. It is something tangible. It proves him a stock hol¬ 
der in the association and as such identifies him with its 
aims and objects and policies, and as trading both under 
its written and unwritten laws as typified by the trade¬ 
mark “Trustworthy Trees and Plants,” besides being 
a receipt for the members’ dues. Like other certificates 
its value is only limited by the success of the Associa¬ 
tion it represents. 
One does not have to draw on the imagination very 
much to see the certificate of membership proudly dis¬ 
played in the catalogues of members in the future. 
The more the Association becomes identified in the 
buying public’s mind, with sound business policy and 
the best nursery practice, the more valuable will mem¬ 
bership become.

INSECTS OF ECONOMIC IMPORTANCE 
By Glenn W. Herrick 
Ibis book was given to a student of horticulture, in¬ 
terested in plants and insects attacking them, to tell what 
she thought of it. 
lor the busy man engaged in fruit growing or veg¬ 
etable raising, or even animal husbanding it is very val¬ 
uable. A fruit grower, for instance, finding the buds of 
his apple trees are being eaten in the early spring by a 
small brown caterpillar need only to consult this book on 
“Insects of Economic Importance” open it to the part 
classified as “Tree Fruits” and under “The Apple” he 
will find a full description of his caterpillar with its life 
history and methods of control. 
The truck farmer raising cabbage need only look in 
this book under “Vegetables” to find the pest of “Cab¬ 
bage” and thus learn to spray his cabbage with an ar¬ 
senical poison, or if it has headed, with white Hellebore 
to control the green worms which multiply and devour 
the leaves so rapidly. 
The book, being small and therefore easy to handle, is 
a ready book of reference for the farmer or gardener 
who can always keep it where it can readily be consul¬ 
ted. 
The work is published by The MacMillan Company, 
New York, N. Y. Price $2.00. 
E. S. Welsh, Shenandoah, Iowa, Robert C. Chase, 
Chase, Alabama, and C. R. Rurr, Manchester, Conn., 
sailed for Europe early in August to make a personal in¬ 
vestigation of the fruit stock situation in France and Hol¬ 
land.
