attached letter: Dear Professor Lorch: At the suggestion of the July 31, 1953 Newsletter of the Michigan Historical Society I am sending you two photoes [sic] of the old lighthouse and adjoining building on Presque Isle, Michigan located on the shore of Huron lake, supposedly the oldest lighthouse on the Great Lakes. It is owned by Mr. F. B. Stebbins, 326 N. Capital, Lansing, Michigan. When through using the photos I would appreciate your returning them directly to him. The following information was given to me by Mr. Stebbins: Built in 1840, through a congressional appropriation of $5,000.- in Presque Isle county, described as, "Where a portage of 200 yards would save 4 miles of canoe trip." Jefferson Davis after graduation from West Point, was supposed to have built it. (According to careful historical investigation, this is not true. There is an article about this controversy in some back number of the Michigan History magazine. Mr. Stebbins feels very strongly about his. He prefers the legend, it sounds bigger). Francis Burgoyne Stebbins purchased from his Uncle Bliss Stebbins in 1930, who bought the property in 1930 from General Duffield of Dteoirt [sic], who had purchased it from the government a short time previously. This light-house was abandone [sic] upon the completion of a new lighthouse in 1872, one mile north from the present location. Adjoining house was used as a summer home. Condition restored in 1936. Lighthouse towe [sic] walls 3 feet thick with handhewn circular stone steps to the top. Signed, Lee H. Gregory

Evolutionary change results from selection acting on genetic variation. For migration to be successful, many different aspects of an animal's physiology and behaviour need to function in a co-coordinated way. Changes in one migratory trait are therefore likely to be accompanied by changes in other migratory and life-history traits. At present, we have some knowledge of the pressures that operate at the various stages of migration, but we know very little about the extent of genetic variation in various aspects of the migratory syndrome. As a consequence, our ability to predict which species is capable of what kind of evolutionary change, and at which rate, is limited. Here, we review how our evolutionary understanding of migration may benefit from taking a quantitative-genetic approach and present a framework for studying the causes of phenotypic variation. We review past research, that has mainly studied single migratory traits in captive birds, and discuss how this work could be extended to study genetic variation in the wild and to account for genetic correlations and correlated selection. In the future, reaction-norm approaches may become very important, as they allow the study of genetic and environmental effects on phenotypic expression within a single framework, as well as of their interactions. We advocate making more use of repeated measurements on single individuals to study the causes of among-individual variation in the wild, as they are easier to obtain than data on relatives and can provide valuable information for identifying and selecting traits. This approach will be particularly informative if it involves systematic testing of individuals under different environmental conditions. We propose extending this research agenda by using optimality models to predict levels of variation and covariation among traits and constraints. This may help us to select traits in which we might expect genetic variation, and to identify the most informative environmental axes. We also recommend an expansion of the passerine model, as this model does not apply to birds, like geese, where cultural transmission of spatio-temporal information is an important determinant of migration patterns and their variation.

Continental margin sediments off Nova Scotia accumulate at high rates (up to 360 cm/kyr) and contain a history of millennial-scale environmental changes which are dominated by the proximity of the Laurentide ice sheet during the latest Quaternary. Using stable isotope ratios of oxygen, accelerator mass spectrometer radiocarbon dating, micropaleontology, and sedimentology, we document these changes in six piston cores ranging in water depth from ab. 450 to ab. 4300 m. We find that maximum d18O in N. pachyderma occurred about 15 ka and preceded the maximum abundance of this species in these cores by ab. 1000 years. Between 13 and 14 ka we find a second peak in abundance of N. pachyderma, minimum d18O, and two pulses of ice rafting. The sediment lithology supports terrestrial studies which indicate that there was a general withdrawal of ice beyond the upper Paleozoic and Mesozoic red beds by 14 ka in southeastern Canada, so the ice rafting events between 13 and 14 ka probably reflect ice stream activity in the St. Lawrence valley. The Younger Dryas event is recognized as a peak in abundance of N. pachyderma and ice rafting (dated as ab. 11.3 ka), but meltwater discharge to the Gulf of St. Lawrence was either too small or occurred over too long a time to leave a distinct d18O minimum off Nova Scotia. At 7.1 ka, in the middle of Holocene warming, we find a third peak in abundance of N. pachyderma and another d18O minimum but no ice rafting. We interpret these data as evidence of a late-occurring meltwater event which, if correct, could have originated in the Great Lakes, in the Labrador-Ungava region, or in both. The final millennial-scale phenomenon off Nova Scotia is the onset of "Neoglaciation," marked by increased ice rafting and increased % N. pachyderma beginning about 5 kyr ago.
