Ten Weeks Sufficient There is no reason why one cannot finish our course in the allotted time of ten weeks, but no charge will be made if more time is required, as we desire above everything to give you such a course that your efficiency will make your work a pleasure. Your work can be done as well thousands of miles away as if you were on the ground at our School. If you contemplate purchasing a machine, you could not do better than to first take our course, when you will be able to judge better on your own account precisely what style of machine is peculiarly adapted to your needs and your particular section of the country. We can be of great service to you in choosing a machine. Some machines are better adapted to certain localities than others; for instance, a hilly or sandy country requires a low geared, light weight, high powered machine, and you can rest assured on getting our unbiased opinion. Our course has been taken by many ladies who own or contemplate owning a machine, and they are among those who are most emphatic in praising our method of teaching.
