This is my translation of the text of the first Labor (5th Grade). As you will have noticed already, I am no professional or native english speaker/translator. But I hope it serves you better than Goolge Translate. It's very hard for me to translate these old texts, as they used very long passages between the sentences. I think that's pretty elegant (the sentences -not my translation) though I am not used to translate these kind of texts.
Text in square brackets are alternative words inserted by me to possibly provide a better understanding. The content in round brackets exists in the original text, but I failed to include it into the flow of the text.
Labor Imus or the attraction of the air-spirit
First the worthy brother has to choose [find] a habitation in a remote, free, slightly elevated place, always filled with fresh air, to prepare inside a comfortable room or chamber , in which exists a window to the Orient: In said chamber all openings have to be well closed and a pane taken out of the one single window pointing towards the Orient, or if there are wooden shutters, one has to cut out a round hole in the diameter of a pan in which is put a big funnel made of glass or white sheet (see Fig. A) from outside. Above the funnel must hang a leaden cover B., which has to be opened with a line when the air is pure and closed when the weather is cloudy. In the end of the funnel a pipe C. of the same Materia and the length of an arm that sharpens towards one end, has to be put, that leads into the canal of the tubulated flask Lit. D, where a wide helmet Lit. E has to be applicated, from which the snout goes into Lit. F. The flask lies in an earthen sand Capelle Lit. G on (symbol of tin), which is standing on a small iron oven Lit. H, like it is clearly shown in the drawing of the machines.
If the air is clean and cool, the cover of the funnel will be opened and a gentle fire is made in the oven, so that the ash only reaches the warmth of the first grade of a B.M. Like this, these calor as an Attractivum will draw [suck] the earth-spiritum (which is hidden from our eyes) with great power and make it visible and touchable in aqua-form very quickly.
But should the air be not cool or tempered, but hot and humid, one must replace the ashes with Sal Communis that is put into a tinnen bowl placed on ice. This way the same effect like with the fire will be observed.
NB. This operation must begin each time at dawn and be ended around the 9th hour.
After the worthy brother has collected a sufficient quantity of this birth giving, feeding and as well consuming and then again birth giving, common world-, air and life-spirit, he has to put it into some clean glasses with ingrained plugs and store them at a cool place until needed. But the glasses have to be completely full, otherwise this alive-making spirit would start its Circulationes in the empty space in between, and exactly like the whole earth arose, when it was created in and out of the water, because the spirit of god was floating there above, this inseperable Quintum esse as a ruler of the beautiful daughters of god (nature) would separate the Terra out of the Aqua at a time that is unwanted now. With the recommendation to the worthy brother, that he preferably undertakes the attraction of the spirit in the first 2 balmy month May and June, we will finish the first Labor and go on from Keter to Chochma.
