AT the end of November, 1915, there appeared in the London Gazette a notice issued by the Minister of Munitions under which power was taken to commandeer all optical instruments of importance for the defence of the realm. Since that date the Ministry of Munitions has been examining the available supply of such optical instruments, both in manufacturers' and dealers' hands. The examination, which has been a very heavy piece of work, had for its purpose the enforcing of certain restrictions placed upon the sale of such instruments under the Defence of the Realm Act Regulations, 1914, and it was recently announced that traders can only offer such instruments for sale if and when they are specially marked. The announcement appears in the January Army Order, in which it is stated that “two marks will be used, one indicating instruments which do not come up to the standard Government requirements, and the other instruments which come up to the required standard but are not required by the Government.”
