with l\n\l stem is (l<>\\ ii licre soiiicwIku'c, down below all these 

 dead leaves. That applies to looking for the disease on the tree, 

 or on the sprouts or suckers Avhich niaj eonie up from the base 

 of a tree. 



No. 17. In very younu;- nursery stock, or the young- sprouts 

 which come up from a tree, or the vigorous growth on a tree, on 

 I he twigs at least, Ave often get this type of the disease at its very 

 beginning. This is often more brilliantly colored than shown in 

 ihis view\ It is very conspicuous indeed, particularly on nursery 

 stock. Although the view does not show any fruiting pustules 

 at all, by cutting into that area Ave get the characteristic mottled 

 mycelium or vegetative stage of the fungus beneath the bark. 



No. 18. NoAv Ave have a branch Avhich shows the withered and 

 yelloAvish leaves. This yelloAV color folloAvs along after the pale 

 green color. It is not a pure yelloAV, as a rule, although some- 

 times it has been quite strikingly of a pure yelloAV color. You 

 Avill notice that the leaves Avither after aAvhile; that is, they 

 crumple up after a time and that crumpling is shoAvn, to a certain 

 extent, in this vieAv; and also the yelloAV color. 



No. 19. A little later Ave have the deeper color. This shoAvs 

 the broAvner coloration around the margin of the leaves. At the 

 left AA'e have tAvo leaves Avhich shoAv merely the beginning of the 

 discoloration. At the right the leaf is someAvhat crumpled, bent, 

 and discolored. 



No. 20. This is a stage much the same as that of the little 

 branch Avhicli Avas shown three views back, this shoAving a larger 

 vieAV of the same thing. 



No. 21. Finally the leaf assumes a somcAvhat brownish tint, 

 Avhich is shoAvn here. The leaves in this condition are often more 

 crumpled and curled up than shown here. These two leaves have 

 been flatt^ied out somewhat so as to shoAv the color. 



No. 22. NoAv to take some of the woodland views, to show 

 hoAV the disease looks in the landscape. Here is a large tree 

 Avhich, OAving to lack of special instruction as to the coloring of 

 it, lacks one or tAvo features Avhich it ought to have. For instance, 

 this branch up here, and that Avhole branch (indicating), ought 

 to have shoAvn the yelloAV broAvn color. The coloring, however, 

 was not noticed in time to give instructions in regard to it. This 

 view, however, is shown primarily to represent the type of tree
