gated his plant for four months, in my leisure time, watching 

 every detail, taking notes, and. going over in conversation 

 with the Doctor and his wife the experiments which had led 

 up to his deductions and settled plans. I made a rough draft 

 from my data, cut out superfluous words and boiled every- 

 thing down, and the following pages are the result. I take 

 no credit for ideas of my own, but merely have made obser- 

 vations of another's work, checked them for accuracy, and 

 written down the result. My intention has been to make 

 a simple guide which faithfully followed by even a child with 

 some gumption will result in a duplication of Dr. Robinson's, 

 success anywhere. He has revised the proofs and aided in 

 the preparation of the illustrations. We hope this little hand- 

 book will stimulate those into whose hands it goes to make 

 a profitable living for themselves and aid in the development 

 of this remarkable home industry. We welcome new facts 

 and new experiences from any source and will take pleasure 

 in incorporating them in future issues of this Manual.
