THE Wairarapa Age MORNING DAILY. TUESDAY, NOVEMBER 19, 1912. THE CASEIN INDUSTRY.

Tho high price of land in New Zealand is compelling farmers, not only to adopt scientific methods for tho cultivation of the soil, but to utilise tlio.se by-products which have hitherto been allowed to go to waste. Tho dairy-farmer, in particular, must needs use every effort to prevent a leakage. It is interesting, therefore, to note what is being done in various parts of the Dominion. The establishment of tho casein industry in tho Wanganui and Manawatu districts opens up a wide field for possible development. The Department of Agriculture has issued the report of Mr J. Pedexsen on his European investigation into the casein industry. It is an interesting and instructive bulletin, and should prove a valuable guide to those of our butter factory managers who may bo called upon to manufacture this by-product, though with the moro general adoption of cheese-making and the rapid expansion of homo separation, the manufacture of casein is never likely to assume considerable proportions in this country. .Speaking of the outlook for casein Mr Pcdersen says: "During tho last few years the use of casein for technical purpose l ? 'has increased remarkably. Tt is especially in papermamifacturo that it has boon utilised, as for this purpose it has been found to bo more suitable than glue. It is now used for making waterproof paper, for coating paper (either matt or glossy), to fasten together individual sheets of paper, and to convert paper pulp into a mouldablo condition. Tho machinery in nearly all the German paper-mills has been altered to suit tho new methods so that only casein can now be used in the process of manufacture. Obnsiderabl« quantities of acid casein ar« also

used in tho manufacture of paints, 0 r i as a glue. Rennet casein is used for 1 the manufacture of galalith of milkstono. Tho chief buyer of rennet casein is tho International Galalith (Gosollschaft, Hoff, and Co., of Harburg, near Hamburg). This firm is also tho greatest manufacturer in Kurope, and, with its branch factories | in France, employ's over twelve hundred men. Various articles are mado from rennet casein, viz., combs, pearls, paper-knives, billiard-balls, and many others. It somewhat ro--1 sembles celluloid, but is free from colour and presents no danger from fire. We cannot expect to realise, in New Zealand the same value for .skimmilk as in Denmark, but we have certain advantages in the manufacture of casein. Most of our factories handle largo quantities of milk, and wo sbould be able to turn out a more uniform than in most countries. Taking everything into consideration, the outlook for casein in New Zealand appears to be good. ' As long as tho quantity is first-class tbe highest market price will be obtained. It should before long become an important factor r iu connection with the dairy industry of the Dominion."
