Steam Boilers, to Prevent Incrustation from Becoming Hara 

 — A bar of zinc having accidentally been left in a steam boiler, when undei 

 repairs, it was afterwards found to have disappeared, or dissolved, by whictj 

 the incrustations, iostead of becoming hard, were muddy and soft, and hencfe 

 easily removed. This proves that the zinc, and iron of the boiler, forms a bat- 

 tery, the zinc being consumed, while the iron is protected, which is claimed to 

 be a valuable discovery in engineering. The size of the bar of zinc would 

 necessarily depend upon the size of the boiler, and how long the run was to b« 

 between cleanings. 



Nails, to Drive Into Hard Sessoned Timber.— The editor of the 

 Mew Oenesee Farmer gives the following account of witneseing an eiperi-

 I obtained from a sewing-machine agent who said he had manufactured and
