Little Wonder Shearing Machine Many hundreds doing good service throughtout Australasia. The Little Wonder is specially constructed for shearing and crutching flocks up to 5000 sheep. It comprises a two H.P. Benzine Engine, well finished and perfectly constructed, fitted with a High=grade Magneto, Hit or Miss type, Sensitive governor, Automatic Lubrication, Water Tank, Power Grinder complete, Oil, Oil Cans, Screw Drivers, Brushes. The Shearing Attachments comprise tubes and cores of good length so that all parts of the sheep can be comfortably reached, also two Latest Model Cooper Handpieces. The Machines are thrown in and out of gear by one stroke of the hand. The Little Wonder is a complete Two Stand Power Installation in itself and gives more real value at the price than any other two-stand portable plant at double the monev. .jyi) The Price of the Little Wonder is 50 Complete as illustrated f.o.b. main ports. Please write to MS or nearest agent for full particulars. COOPER COMBS AND CUTTERS will fit any make of handpiece, cost less, and are better than any other. See that you get the "COOPER."

THE FAMILY CRACIDAE, including the curassows, guans, and chachalacas, ranges in the present day from the lower Rio Grande Valley in Texas south to Argentina. The modern distribution of the family gives no clue to the considerable radiation once enjoyed by the group in what is now temperate North America. Fossil species are known from Tertiary deposits in Florida, Nebraska, and South Dakota. This paper describes a new fossil cracid, older than any previously discovered, from the top of the Chadron formation, lower Oligocene of South Dakota. The fossil is preserved in fine-grained, freshwater limestone. Preparation of the specimen in high relief has exposed all of the major skeletal elements except the skull and most of the vertebral column, which probably became disarticulated before the specimen was finally buried although they may lie buried in the slab. The bones, lying more or less in a single plane, are well preserved, although many of the larger ones are moderately to severely crushed. Judging by the fairly close association on the slab of most of the toe bones and the proximity to each other of the limb bones of right and left sides, it seems that the skeleton was partly articulated when buried and that much of the bird was decomposed. Some shifting of individual bones occurred as sediments accumulated over the fossil.

Hail impact-induced erosion has the potential to significantly affect the operational lifetime of structures exposed to extreme weathering environments such as hail events. Computational materials modelling can be used to better understand the erosion behaviour during a hailstone impact, and here the relevant background work is detailed. In this paper, an implementation of an ice impact model, utilising Smooth Particle Hydrodynamics along with a highly strain-rate-dependent material model, is shown, and its results and limitations discussed. An overview is given on the literature on modelling hail events, including the history of experimental work. The various potential modelling methods which have been developed is then given, along with an evaluation of the suitability of the methods to future work in this area.
