AMERICAN FORESTRY' 



In this connection, and in relation to the natural de- 

 sire to accumulate from the ends of the earth new field 

 plants for our agriculture, and new fruits for our orchards, 

 and the novelties and curiosities of the i^lant world for 

 our gardens, lawns and parks, it must not be lost sight of 

 that we have first to consider the safeguarding, that is, 

 the conservation of the big commercial crops of America 



THE SAM JOSli, OR CHIXESE, SCALE (A^l'DITU^ PERNICIOSUS) 

 ENLARGED 



Probably no other insect has received so much notoriety as this species. Its 

 international importance is indicated by the vast amount of interstate and 

 foreign legislation which has been enacted relative to it. Millions of dollars are 

 expended annually in efforts to control this pest, which is so injurious to deciduous 

 fruit trees. 



such as wheat, com, cotton, potato, ajiple, peach, orange, 

 etc., and our enormous natural forests which arc and must 

 always remain our chief productions. The risk to these 

 standard products of our soil with all introductions of 

 allied or varietal plants, and especially such plants from the 

 hitherto little exploited portions of the earth, is enormous, 

 as the illustrations alreadj- given have shown; and there- 

 fore all introductions should be preceded by studies and 

 explorations to determine the risk, if any, in advance of 

 the importation; and such importations shoxold, further- 

 more, be surrounded with all restrictions and safeguards 

 necessary to prevent the entry therewith of new plant 

 enemies. In other words, the safeguarding of our big 

 established productions should be the first and leading 

 consideration. 



NATURAL GRAFT ON CORK ELM 



By Guy Caldwell 



DOES any lover of trees pass by a phenomenon known 

 as natural graft without entertaining the wish to 

 know just what accident or set of circumstances 

 evolved to bring about the fortuitous gro^^■th' The cork 

 elm {Ulmtis racemosa) herewith was pointed out by the 

 owner, Mr. Brockenbrough, on his summer place near 

 Richmond, and its clean, healthy condition, together with 

 the unusual symmetrical lines dividing the trunk with such 

 nicetv at once called forth admiration for the wonders of

 This elm, on the summer place of J. M. Brockenbrough, near Rich- 

 mond, is attracting considerable attention. The man in the picture 

 is Guy Caldwell of Richmond, a tree expert. 



nature. It is an interesting speculation to try and im- 

 agine ju.st what incident in its life's history caused the 

 union of these young branches after they had previously 

 come to the parting of the ways. Perhaps they believed 

 that "In union there is strength." 



TREES WITH A HISTORY 



IS there a tree with a history in your town? 

 What do you know about it? Is it being 

 cared for or is it being allowed to die? AMERICAN 

 Forestry would like to know about such trees 

 and would be glad to receive pictures and articles 

 not to exceed 100 words about such trees. Such 

 as are available will be printed in the magazine 

 from time to time.
