Renewal of Main Arms and Stem. 



Although the necessity for renewing these practically permanent portions 

 of the vine is more remote than that of the secondary arms, the occasion 

 does arise. IVlain arms can be replaced in the same manner as the secondary 

 arms by establishing the base of a new arm from a suitably-placed water 

 shoot. With trellised vines it may necessitate the use of a stout water shoot 

 rod which will be trained along the wire to replace a worn-out or injured 

 main arm. Upon this the secondary arms are afterwards built up. (See 

 Fig. 8.) 



Reconstruction of the whole vine by creating a new stem is the least 

 likely, but, for various reasons, a possible necessity. Assuming that there is 

 sufl&cient .vigour in the root system to force out good water shoots low down 

 upon the old stem, one of these can be utilised to re-create the framework of 

 the vine. The growth from such a cane i« very strong, as a rule, and until 

 it becomes stout enough to suppoi't the weight of the young growth, should 

 be securely staked or tied to a trellis wire. In either case the growth 

 selected is cut back to such a heiglit that its growth will serve to form the 

 main arms of the new stem. From this point the whole structure of the 

 vine has to be rebuilt step by step. (See Fig. 10.)

Cement Necessary for 8,000-gallon Tank. 



The following directions were supplied by the Works Overseer to a corre- 

 !- pendent asking for particulars as to the quantity of cement necessary in the 

 construction of an 8,000-gallon overground concrete tank : — 



A tank 12 feet in diameter would be required, with an inside depth of 

 10 feet, the concrete 9 inches thick, and the reinforcement about 2 inches from 

 the outer face, including the bottom. The joining- of bottom and walls 

 would need to be carefully done. The stone (preferably crushed) should not 

 be larger than 1| inches, and should be mixed with sharp, clean sand. Three 

 bags of cement should be used to each cubic yard. The necessary quantity 

 of cement (including that for facing the walls and bottom) would be sixty bags. 



Stamping Eggs tor Cold Stohage. 



The practice of stamping eggs for purposes of advertisement or guarantee 

 appears to be gaining favour with poultry farmers. Replying to a Seven 

 Hills correspondent, who wished to know if the stamping of his eggs before 

 they were put in cold storage would in any way harm them, the Poultry 

 Expert wrote : — The only ill effect that could result from stamping eggs 

 sent into cold storage would be from the ink running or smudging with 

 moisture, thus making the eggs appear unsightly when they came out. 

 Having in view the fact that eggs become moist on withdrawal from cold 

 storage, the smaller the stamp and the less ink used the better.
