ARTIFICIAL IVORY.--A substance resembling ivory of creamy whiteness and great hardness is made from good potatoes washed in diluted sulphuric acid, then boiled in the same solution until they become solid and dense. They are then washed free from the acid and slowly dried. This ivory can be dyed, and turned, and made useful in many ways. DR. GORDON STABLES, the well-known author, spends the summer in going about the country in a caravan. His handsome home on wheels is called "The Wanderer." It is drawn by two capital carriage horses, and is fitted in most luxurious fashion. He takes a man-servant with him, and has a tricycle attached to the vehicle. He stops at night by the roadside. NEW GOLD FIELD.--A rich gold field has been discovered between the two rivers, Lava and Papanahoni, in Surinam. It is an open question whether this district of 20,000 to 25,000 square kilometres belongs to France or Holland. M. Condreau, the French traveller, who has been closely investigating the district, considers that it will be as productive as the gold-fields of Australia and California. MR. GEORGE LE FÈVRE, of the Huguenot Church at Canterbury Cathedral, writes thus--"A large and valuable oil painting of a scene in the history of the Huguenots has been presented to the French Church. The subject is exceedingly appropriate this year, being the tercentenary celebration of the defeat of the Spanish invasion of England. The picture has been hung up in that part of the Crypt known as the Chantry of the Black Prince, and has been much admired by tourists, who are now visiting in considerable numbers." BY the steamship _Oonah_, which is the latest addition to the fleet of the Tasmanian Steam Navigation Company, there arrived at Melbourne on Saturday, April 28th, from Tasmania, the largest shipment of fruit for the London market which has left the Australian colonies--about 13,000 bushels of choice apples. The fruit will be transhipped into the cool chamber of the P. and O. mail boat _Oceana_, leaving on the 4th of May, and will be followed by another shipment by the _Britannia_, leaving on the 18th of May. This, we understand, closes the operations of the shippers for this season. Should the outcome of these shipments be as encouraging as the telegraphic news already received seems to indicate, there is every prospect of a very large export trade in this industry being established. We are informed that the parcel now arrived could have been very much increased had there been more room in the cool chamber of the _Oceana_. No doubt next season all the boats of the P. and O. and Orient Companies will make arrangements to take fruit, so that shipments can be forwarded every week.--_Launceston (Tasmania) Examiner, May 2nd._
