unknown part of the world, what a prize the traveler 

 would have to bring home, and what interest it would 

 excite among botanists ! 



In photographing delicate flowers like the Horse-mint 

 (Fig. 3), we apply the same principles set forth in the 



THE SPINY LIZARD OF AUSTRALIA 



Figure 9. Many curious animals are found in Australia, and this is one 

 of them. It is also known as the Moloch or Mountain Devil. One would 

 hardly suspect this of being a dead specimen, and it is a good example 

 of what may be done with such material by the aid of the camera. 



case of the shells, although flowers constitute far more 

 difficult subjects to deal with, as many of them wilt as 

 soon as gathered. To obtain the correct point of view 

 demands long study and experience; and the traveler 

 must be familiar with the use of the color-screen, in as 

 much as he is not likely to have orthochromatic plates 

 with him. 



When properly taken, large and showy flowers are 

 beautiful photographs for the traveler to bring back with 

 him ; and when they are rare or unknown, he will be 

 surprised at the amount of interest they will excite in 

 many quarters. They may be so photographed as to ex- 

 hibit nearly all the peculiarities of their structure, as in 

 the case of the one here shown in Figure 4, which is- a 

 blossom of our Poplar Tree, so familiar to most of us in 

 the Eastern States. 



In the case of some plants, it is highly desirable to 

 show the roots when possible, and to pose at least one 

 leaf, in that its form may be shown, as in the case of the 

 Aquatic Joint Weed in Figure 6; this is exceedingly im- 

 portant, and should ever be borne in mind. Often, when 

 pictures are taken from the wrong point of view, they 

 are not only useless and inartistic, but of little value to 



students and botanists. American Forestry has pub- 

 lished many an excellent example of how to obtain suc- 

 cessful photographs of plants growing in their natural 

 habitat. Such pictures are frequently of great value ; 

 and the more the traveler secures, the better the subjects 

 representing intelligent results. And think for an in- 

 stant what one hundred such as is here shown in Figure 4 

 would mean, obtained in the heart of New Guinea! 

 As a rule, all sorts of insects are far more difficult 



A GREAT INSECT PEST 



Figure 10. Here we have a good view of one of the greatest insect pests 

 in the United States, the tent caterpillar, full-grown, with three of the 

 white cocoons this species makes. The beetle is one of the "searchers," 

 and preys on caterpillars. 



subjects to secure good photographs of than are 

 flowers, while they are equally interesting and valu- 

 able. The difficulties are due chiefly to the fact that 

 it is not easy to pose them properly in order to get the 

 best scientific photographs. Then their being generally 

 alive, their movements are often difficult to deal with. 

 and those movements are of so many kinds. Often 

 caterpillars will not remain quiet for an instant ; grass-
