 laid across the top of the Ijarrel no fur- 

 ther attention will be required. In 

 another vessel slack 4 pounds of lime, 

 using care in order to obtain a smooth 

 paste, free from grit and small lumps. 

 To accomplish this it is best to place 

 the lime in an ordinary water pail and 

 add only a small quantity of water at 

 first, say a quart or a quart and a half. 

 When the lime begins to crack and 

 crumble and the water to disappear 

 add another quart or more, exercising 

 care that the lime at no time gets too 

 dry. Toward the last consider-able 

 water will be required, but if added 

 carefully and slowly a perfectly smooth 

 paste will be obtained, provided, of 

 course, the lime is of good quality. 

 When the lime is slacked add suffi- 

 cient water to the pas;e to b;ing the 

 whole up to 2.5 gallons. When the cop- 

 per sulphate is entirely dissolved and 

 the lime is cool, pour the lime mi k 

 and copper su'phate solution slowly to- 

 gether into a barrel holding 50 gallons. 

 The milk of lime should be thoroughly 

 stirred before pouring. The method 

 described insures good mixing, but to 

 complete this work the barrel of liquid 

 should I'eceive a final stirring, for at

 changed, it is safe to conclude that the 

 mixture is as perfect as it can be 

 made." 



Complete directions for preparing 

 Bordeaux mixture may be found in 

 Farmers' Bulletin No. 38 on "Spraying 

 for Fruit Diseases." In the same bul- 

 letin also directions may be found for 

 applying the mixture. A hand syringe 

 is very unsatisfactory, as it very soon 

 clogs up, but a cheap spray pump, 

 costing from $3.00 to $5.00 may be ob- 

 tained of any hardware dealer. This 

 pump with an occasional packing of 

 the valve will last for years and may 

 be used for many different kinds of 

 spi'aying. Suggestions as to the pump 

 will also be found in the bulletin men-

"It is now necessary to determine 

 whether the mixture is perfect — ttat 

 is, if it will be safe to apply it to the 

 tender foliage. To accomplish this, 

 two simple tests may be used: First 



insert the blade of a penknife in the 

 mixture, allowing it to remain there 

 for at least one minute. If metallic 

 copper forms on the blade, or, in other 

 words, if the polished surface of the 

 steel assumes the color of copper plate, 

 the mixture is unsafe and more lime 



GRAPES CRACKING, 



This defect is evidently caused by an 

 overflow of sap to the berries, which 

 is generally enforced by too close 

 pinching of the sub-laterals, accompa- 

 nied with high temperatures and ex- 

 cessive atmospheric moisture, and 

 much feeding at the root. And again 

 if the house is shut up close, and the 

 night temperature is allowed to run 

 to 75 or 80 degrees, which it will do, at 

 the season when this grape begins to 

 take on color, the condensation on the 

 berries in the morning is sufficient to 

 crack the fruit, if the foliage is at all 

 defective. And if the canes are old- 

 established ones, too deep rooting 

 may be the cause of the trouble. And
