38 EIGHTEENTH ANNUAL REPORT OF THE 



Mr. Dadant. — This was 38 years ago. There is probably some 

 improvement. 



The President. — On the whole it is correct. The only thing 

 they are doing to-day to make glucose is carrying the process a little 

 farther and using the enzyme that occurs in the sugar to break up the 

 maltose into simple sugar. The golden diastase is pure, and the pure 

 does not contain the free acid, but you do not find that usually com- 

 mercially on the market. It is being used for certain preparations, 

 certain products, trying to take the place of sugar. But in forming 

 the corn syrup in this country — one of the most prominent ones to-day 

 is Karo — ^which is made by boiling corn starch in sulphuric acid and 

 remove the sulphuric acid after the boiling is completed by precipita- 

 ting it with calcium carbonate, which forms calcium sulphate. It is 

 then filtered back through the precipitate, and you will have your syrup, 

 which ferments if you dont leave a little acid in it to stop action of any 

 enzyme which might not be killed, and then they add some carbon 

 bi-sulphate, which is a poison which we use to kill wax moth." This 

 also helps to keep the liquid from turning brown. You can remove all 

 lime salts and remove all acid and retain your diastase, which is your 

 glucose. Now, as has been said, you can have the syrup crystaUize 

 any time by the evaporation of the water, but it is a conglomerate 

 mass, just diastase and maltrose and calcium sulphate and some of 

 this carbon in it, it is not good for man, insect or beast. 



Mr. Dadant. — That calcium sulphate is chalk. 



The President. — Yes, chalk or lime. 



Mr. Ressinger. — I tried the experiment on tea, with this sugar, 

 but I could not get a dark color. 



Mr. Dadant. — It is better than it used to be. 



The President. — You had then the crystallized glucose, only 

 pure glucose left, but it is not a good food for me, it is not a good food 

 for you, for the simple reason that it is not a balanced ration, it does 

 not contain the "left hand" sugar, the levulose. When you take diatase 

 into your system, very little of it is absorbed; it does not pass through the 

 intestinal tract; sugar passes through the intestinal walls if levulose 

 is present, but will not do this if levulose is absent. Now the bee — I 

 cannot give you all the digestive processes or the forms that it takes 

 in the bee, but he must have a balanced ration, just the same as you 

 must. That is true of all organisms, and it must have this levulose 

 in order to use the diastase. 



Question. — Is honey dew a good honey to stimulate brood rear- 

 ing? 



The President. — Is there any one here who thinks he can answer 

 that? Mr. King has had some experience with honey dew. 



Mr. King. — Well, it is not a good honey, no, but it will do. 



Mr. Dadant. — I wish to object to the statement that it is a 

 dew. The greater part of the honey dew that we get is a product of 

 plant lice. Now, I want to state to you gentlemen that I was of an 

 entirely different opinion for a number of years, because I had never 

 seen lice on the top of the leaves, and the dew is on top of the leaves, 

 and one day in passing through the woods where there was more or 

 less honey dew, I found three dead leaves, dried up and shriveled.
