Part XIII AMERICAN WOODS takes up tropical species finding 

 their northernmost limit of distribution in southern Florida, which is 

 distinctly tropical in its flora. These woods we have found most 

 interesting and some of them entirely at variance with the commonly 

 accepted ideas of wood-structures. In several of them there is an 

 absence of annual rings, in one even an absence of medullary rays 

 extending from year to year, and its "annual rings" are broken, some- 

 times with ends overlapping; in another there is a remarkable inter- 

 mingling of firm wood-tissue and a very weak, pith-like, cellular tissue. 



An innovation in Part XIII, which is an added feature of consid- 

 erable interest, is a series of photographic illustrations of typical 

 trunks, showing characteristic barks and natural environment. A one- 

 foot rule was affixed to the trunk, to indicate size, and a few sprays of 

 foliage placed at the base, before photographing. These are doubt- 

 less the first pictures that have been made of these interesting subjects 

 and are similar to the bark pictures of the northern trees which appear 

 in our HANDBOOK OF TREES, described on the last page of this 

 circular. 



As the species which appear in Part XIII range generally far into 

 the tropics, we are bringing out this work also with distinct style of 

 binding and title page, as "Tropical Woods of Florida, the Bahamas, 

 West Indies and Central America," designed for sale in those regions. 

 Owing to the cost of production we are obliged to charge $ 1 0 for it 

 in this^ special form. The price as one of the series. AMERICAN 

 WOODS, is quoted above. Parties holding it in special binding and 

 desiring to acquire the series will receive full credit on returning it to 

 us with order for the series.

Two of the twenty-five trunk pictures in AMERICAN WOODS, 

 PART XIII, illustrative of characteristic barks, foliage and natural 

 environment : 



FIG. to. MAHOGANY. FIG. 12. INK-WOOD 



(Sii'ielcnia niahagoni Jacq.') (Exothca paniculata Radlk.) 



The straight line to the left o( the Ink-wood trunk is the taut root of a Sirangle-trec, which had begun life on a 

 of the Ink-wood, and would undoubtedly have strangled it in time had not the tree been taken for our sections.
