FEBRUARY AND PLANT-LIFE STILL SLEEPS IN NORTHERN CLIMES

the big fellow here shown in Figure 9, and note how it 

 towers among a perfect army of different species of 

 olants, every one of which has gone to seed several 

 months or more ago. Nearly all the seeds of this 

 plant have been borne away by their feathery tufts, 

 and there is scarcely a single meal left for some soli- 

 tary goldfinch that may, with his long undulating

dips a-wing, come that way. One naturally associates 

 these goldfinches with the thistles-gone-to-seed occasion- 

 ally so vividly that it requires no stretch of the 

 imagination to hear their plaintive notes, although 

 the little black-and-yellow fellows may be nowhere 

 near. This is especially the case when the plants are 

 growing in masses, as they are here shown in Figure 10. 



Aside from studying flowers when they are in the en- 

 joyment of their perfect and normal condition, there is 

 another most interesting chapter in their lives which 

 deserves our earnest consideration and exhaustive re- 

 search. Reference is made to their diseased states, or 

 other manifestations in them indicating various departures 

 from the healthy ones. This is a very large and very 

 important subject, and much attention has already been 

 paid to it by phytopathologists, or those who take into 

 consideration the diseases of plants, shrubs, and trees. 



Diseases of a great many different natures may attack 

 any part of any vegetable growth as the stem, the 



trunk, or any of the branching portions. Flowers, seeds, 

 pods, leaves, roots, bark indeed any of the numerous 

 structures of plants are subject to disease, to the attacks 

 of parasites, to fractures or other injuries, burns and 

 scalds, lightning strokes, strangulations, impact of foreign 

 bodies, drowning effects of excessive solar heat, and many 

 other liabilities. In Figure 11 we have an example of 

 the effects of an attack on the part of some parasite on 

 the leaves and flowers of the common wild Sunflower. 

 In a previous number of American Forestry it was

shown how oak-galls were produced through the attack 

 of certain species of insects, and what an important in- 

 dustry resulted from ascertaining the value to man of 

 these products. 



February, especially in the more northern State's, is the 

 month when the owls make themselves heard in the land.
