 in the preparations throughout. 



The shipments to the Desert Laboratory came through safely 



The regions visited by Dr. Rose and myself during the trip 

 were easy of access and many of the localities had been previously 

 seen by Dr. Pringle, Dr. Rose, Prof. Trelease or other botanists. 

 We had almost constantly in view, however, mountain ranges and 

 valleys from which no specimens have ever been obtained and in 

 which no examination has been made of the flora. In fact, this 

 applies to the greater part of southern Mexico not directly ac- 

 cessible from the railways and stage lines. It would be safe to 

 say that not more than one-tenth of the main topographical regions 

 of southern Mexico have been explored by the botanist. Some 

 of this territory might be reached from haciendas, but the greater 

 part may be investigated thoroughly and profitably only by means 

 of a small independent expedition carrying its own outfit and 

 supplies, as most of the country has nothing beyond the resources 

 of scattered Indian villages in which the traveller is apt to meet 

 with little beyond "no hay" and the tardy service of a people 

 living in the very home and seat of the spirit of "manana."

THE RAPID GROWTH OF THE YOUNG 

 PAULOWNIA. 

 The tree from which the accompanying illustration was made 

 was purchased early in May, 1905, and placed in its present posi- 

 tion near the drinking fountain but a short distance southeast of 

 the Museum. It was a rather sorry looking object upon its 

 arrival, and at that time did not appear to have before it a long 



the sequel here will show. The tree was planted and the first 

 year made two new shoots from the roots, one of which was re- 

 moved. The wonderful growth of this one shoot during the
