Page 45 - BOTANICAL EXPLORATION IN ECUADOR During the year a plan for a co-operative investigation of the flora of northern South America was organized by the United States National Museum, the New York Botanical Garden, and the Gray Herbarium of Harvard University. It is believed that this investigation will greatly enrich our botanical collections and furnish information regarding economic plants which will be of much value to the horticultural and agricultural interests of this country.

(1) That there is an intimate relation between solar changes and meteorological changes of short period, and that measurements of solar radiation like those made by Dr. Abbot and his associates have the greatest importance for meteorology (2) That there is a class of meteorological changes which have their origin in equatorial regions and by a transference of air, probably in the upper layers, are felt within a few days in higher latitudes. These changes are the complement of the complex meteorological...

Mr. Robert Aschemeier, an assistant taxidermist on the Museum force, was detailed to accompany the party. It was decided that the expedition should be known as the " COLLINSGARNER CONGO EXPEDITION, IN THE INTERESTS OF THE SMITHSONIAN INSTITUTION.
Page 269 - Accordingly, there should be found some correspondence between annual changes of the solar constant and annual magnetic changes. This is found to be the case. Since the solar-constant changes occur only approximately in accordance with sun-spot activity, and since the magnetic changes are found to conform closely to those in the solar constant, an explanation is found as to why the irregularities in the magnetic secular change do not always synchronize with changes in solar activity as measured by...

In continuance of the search begun in recent years for large exhibition museum specimens to illustrate the various phases of structural geology and stratigraphic paleontology, Drs. Bassler and Resser, of the division of paleontology, report as follows: Field work was begun with an investigation of the Cretaceous rocks of western New Jersey, where the prime object was to secure suitable exhibits of such economically important rocks of organic origin as glauconite, or greensand,...
Page 68 - Ainsworth Means, honorary collaborator in American archeology, US National Museum, reached Peru to do archeological work. A short time was first spent in the vicinity of Lima, during which were studied several ruins about the capital, under guidance of Drs. Jose de la Riva-Aguero and Julio C. Tello. Two of the least known places visited were Maranga and Pando. They are very close together and are about 6 miles northwest of Lima. In its prime, Maranga (see fig. 76) had four fine terraces with a spacious...
Page 120 - More than 250 fragments of pottery were collected, no of which were pieces of the rims and necks of jars. The decorations of these were not unusual in character, showing various imprints of roulette, twisted cord, woven fabric, sharp stick, or thumb-nail, but these were combined in such variety that only three or four duplicates were found in the entire collection. Thirty-four fragments of jars were large enough to show the curve of the sides and the size, which varied from a few inches to about...
