Electronic Structure of the Heaviest Elements
All of the available evidence leads to the view that the 5f electron shell is being filled in the heaviest elements giving rise to a transition series which begins with actinium in the same sense that the rare earth or 'lanthanide' series begins with lanthanum. Such an 'actinide' series is suggested on the basis of evidence in the following lines: (1) chemical properties, (2) absorption spectra in aqueous solution and crystals, (3) crystallographic structure data, (4) magnetic susceptibility data and (5) spectroscopic data. The salient point is that the characteristic oxidation state (i.e., the oxidation state exhibited by the member containing seven 5f and presumably also by the member containing fourteen 5f electrons, curium and element 103) is the III state, and the group is placed in the periodic table on this basis. The data also make it possible to give a suggested table of electronic configurations of the ground state of the gaseous atom for each of the elements from actinium to curium inclusive.

The Path of Carbon in Photosynthesis IV. The Identity and Sequencefo the Intermediates in Sucrose Synthesis
The synthesis of sucrose from C{sup 14}0{sub 22} by green algae has been investigated and the intermediates separated by the method of paper chromatography. It is shown that sucrose is the first free sugar appearing during photosynthesis. It is apparently formed by condensation of the glucose-I-phosphate and a fructose phosphate. A series of radioautographs of paper chromatograms of extracts from plants which have photosynthesized for different periods of time has been prepared. The results indicate that 2-phosphoglyceric acid is the first product synthesized from C0{sub 2} during photosynthesis.

Photograph of an aerial shot of Owl Creek Detention Reservoir site #1 and the surrounding area. The back of the photograph proclaims, “Owl Creek Ok-SCD-13-Wa.2. Site #1. Detention Reservoir. Drainage area – 500 acres. 81.0 acres in cultivation; 334.0 acres in pasture, range, woods; 85.0 acres in abandoned cropland – revegetated. Excellent cover on grassland provides silt screen for water from cultivated land. Note all cultivated fields were terraced when picture was taken. Permanent storage: 1.10. Flood storage: 4.18. Peak flow: 900 c.f.s. Release rate: 23 c.f.s. Detention reservoir protects 700 acres. Flood drainage benefit ration 66:1. Note farm ponds on main branches of drain above this reservoir.

Owl Creek Detention Reservoir Site #4
Photograph of an aerial shot of Owl Creek Detention Reservoir site #4 and the surrounding area. A road runs vertically on the left side of the photograph. Furthermore, a small house stands next to the road in the upper left. The back of the photograph proclaims, “Ok-SCD-13-Wa.2 – Owl Creek Detention Reservoir Site #4. Redish [sic] Prairie Land Resource group. 70 acres in cultivation, 220 acres in pasture, range, woods; 10 acres in abandoned cropland. Excellent cover on grassland. In foreground abandoned cropland has been revegetated. At right geological erosion has been greatly retarded by good grass and controlled vegetation. Permanent storage: 1.13 in. Flood storage: 4.10 inches. Peak flow: 490 c.f.s. Release rate: 12 c.f.s. Acres of bottomland protected: 700 acres. Flood drainage benefit ratio: 6.6/1. Near top of photo the main drain appears to continue up (north) and beyond the field of the camera. Actually this drainageway drains in the opposite direction startin [sic] ¼ from top of photo.”
