Parcels from the same blend were carded and spun at different mills and on different types of machines. The yarns and cloths were tested for strength and the behaviour of the cloth during the milling operation was observed. The variations in strength and count revealed were greater than some members of the trade expected, but, since the yarns were spun in a normal commercial manner, the results may be regarded as fairly representative of current practice. It is shown that, provided the yarns are weavable, the variations in the cloth are smaller than those in the yarn, and the weaker yarns do not necessarily give the weaker cloths. With regard to the output of tape condenser machines, the important conclusion is drawn that much greater outputs than are commonly obtained are possible. Generally, alterations would be necessary to get sufficient rubbing to admit of the larger outputs. Those members who are interested are recommended to experiment in this connection. The results as a whole are very difficult to interpret on account of the large number of variables, not only in the machines, but also in the individuality and experience of the carding engineers. For this reason it is sati
