It is believed that a certain amount of justice is attached to this objection to lime and sulphur as generally used ; unless, therefoi-e, lime and sulphur can be used in a way which will not injure the wool to an appreciable extent, we should advise against its use in certain cases; in certain other cases the good accomplished far out- weighs the injury it does. Let ns, therefore, examine into this damage and its causes. The usual time for dipping sheep is shortly after shearing, when ihe Fig. 258.—A more advanfced case of conniion scab. wool is very short; whatever the damage at this time, then, it can be only slight, and the small amount of lime left in the wool will surely do but little harm. In full fleece lime and sulphur will cause more injury. In Australia the deterioration was computed by wool buyers at 17 per cent., although in Cape Colony the Department of Agriculture maintains that if properly prepared, and if only the clear liquid is used, the sediment being thrown away, the official lime-and-sulphur formula will not injure the long wool. The United Slates Bureau of Agriculture have found some samples of wool injured by dipping, while on other samples no appreciable effect was noticeable. If a lime-and-sulphur dip is used, care must be taken to give the
