An Inquiry addressed to the publisher, Paterson, New South Wales, might result In obtaining the information. “ Boatman,” Dunedin. —To make headway against the tide a boat must travel faster than the current. (2) The speed of the current between Quarantine and Goat Islands varies. Neap tide will be two knots: spring tide, three to four knots. " A Subscriber,” Owaka.—A farmer may prospect for gold on his own.land, but no person can sell gold without a minor’s right. >2) No person can prospect for goid on freehold property without the consent of the owner, who can therefore arrange conditions respecting any discovery of gold. " Bulbs," Tahakopa.—The postage in three , dozen gladioli bulbs from England would depend on the weight of the parcel. From 4s to 5s Od should cover it.

W., Dunedin.—At the general election on November 4, 1925, the Reform Party was returned with 53 members. Labour 12, National 10, Independent 2, Liberal 1. During the existence of that Parliament Reform lost two seats to Labour and the National and Liberal Parlies (holding 11 .seats) became the United Party. Sir Joseph Ward, who held the distinction of being the solitary Liberal In the House, led the United Party to (he polls. The election was held on November 14, 1928. The Reform Party won 29 seats, United 27, Labour 19, and the Independents 5. The United Party, with the aid of Labour, came Into office. Before the next election took place Labour had increased its strength by one member, and the Reform and United Parties then holding 51 seats between them became the Coalition Party. At this time there were 20 Labour members, eight Independents, and one Country member. At the last election In 1931 the result was as follows: —Coalition 47, Labour 24, Independent 4, United 2, Reform 2, Country 1. "Big Jim," Walplata.— (1) We assume that your question relates to the correct method of holding a shovel while shifting earth. A right-handed man has his right hand near the centre and the left near the end of the handle. If shifting earth from the ground he will use his right leg at a , point just above the knee as a lever. (2) No person knows definitely what mental process differentiates man from all other animals and whether animals think. There are degrees of Intelligence In both man and animal as a class, but there are definite attributes possessed alone by man. It Is assumed by some than animals cannot reason, but quite Intelligent people have proved at least to their own satisfaction that in certain eases animals could not have acted as they did without in some measure exercising a reasoning faculty. When man can claim to know everything that goes on In the head of an Intelligent dog, for Instance, it may be possible to supply an answer to a very Interesting speculative question. (3) Tho pressure is greatest on the longer pipe, that which carries the water to the top of the tank. The pipe which enters the bottom of the tank has the pressure only of the water in It and the weight of water equal to Its diameter. Greater pressure Is required to pump water Into the top of the tank because of the longer distance. The pressure becomes equal on both pipes when the tank is practically full.
