CORSE OF HUMAN PARASITES. 385 



month, each, for four months past. We shall run the factory till 

 the first of November, or a week over five months. Good cows 

 make 500 pounds in the course of the season. We are selling at 

 15 cents per pound. It costs a cent and a half to manufacture. 

 So you can see what we are doing." 



I have but a word to add, and that is to say that, this is an 

 excellent record. Sixty thousand pounds from two hundred cows, 

 is three hundred pounds each, in five months and one week, and 

 they probably yielded some milk before and after, and perhaps 

 during these months which was used at home. 



When I visited the dairy sections of the principal dairy States, 

 I found occasional instances of cows giving five, six and even 

 seven hundred pounds of cheese per annum, but the average did 

 ,not exceed the amount stated to be obtained at Strong, and this, 

 be it remembered, in a section where the business has just been 

 begun, and we may presume where attention has not yet been 

 very much directed to the selection of cows especially for this 

 purpose, nor to feeding specially with a view to production of 

 milk. I regard these facts as confirming the opinion long held 

 that the manufacture of cheese may be made a very remunerative 

 pursuit in our good grazing districts. 



Mr. J. W. Lang of Waldo county then read the following, on 



The Cukse of Human Parasites. 



By parasites here, we do not wish to be understood to mean 

 those lesser tribes of insects and worms internal or external, for 

 an abler pen than mine has thoroughly canvassed that subject, and 

 if you will take the pains to consult the Report of the Secretary 

 of the Connecticut Board of Agriculture, for 18*70, you will find 

 an excellent paper therein, by Prof. A. E. Verill of Yale College, 

 entitled, "Internal and External Parasites of Man and - Domestic 

 Animals." This paper is full and exhaustive, and is illustrated 

 with cuts, an accomplishment I despair of, except such cuts and 

 pen and ink portraits I may be enabled to present. Such as I 

 have are at your service. 



The human parasites that I design to treat somewhat upon, are 

 in the form and semblance of men, that subsist upon the varied 

 forms of industry and upon the producing classes, without aiding 

 them, very much as the eagle feeds upon the fish-hawk's prey. 

 These parasites are to be found everywhere, and almost every
